    Romania - Last active: 19 days ago - Tests: 8 - Portfolio: 9

    Experience makes the difference between the average and the excellent. In creating online experiences that matter, you need a dedicated professional who works hard and has native skills - qualities I own and use with great respect towards the team I work with and your audience. How can your presence be different, unique and appealing in an online environment many times ruled by cliches and patterns? By adapting rules and innovating according to your distinct needs. By believing in all the differences people share and striving to customize your online presence accordingly. From the name of your company to deploying a project, your business has to speak to various people's needs and relate to their feelings. By helping you communicate who you are through a reliable online experience from start to finish, I support your causes and give others reasons to believe in you. If you feel we're on the same length, than we have a professional future together and I'm looking forward to sharing my skills and commitment with you and your business.

    Direct-Response Copywriter

    United Kingdom - Last active: 1 day ago - Tests: 4 - Portfolio: 7

    If you’re doing business online but aren’t working with a professional copywriter, I guarantee you’re leaving money on the table... Let me show you... “How You Can Add An Endless Stream Of Cash-In-Hand Customers To Your Business Without Spending A Penny More On Advertising” My name’s Joe Atkins. I’m a professional copywriter and one of Upwork’s top-ranked, and most recommended freelancers. As well as being a student of AWAI’s Copywriting Masters program, I’ve also spent hundreds of hours learning from direct-response copywriting legends such as: Gary Halbert, Bob Bly, John Carlton, Dan Kennedy, Clayton Makepeace... just to name a few. Copywriting is not just my job. It’s a passion that I live and breathe. And thanks to the experience I’ve gained, my results have been stellar... * A sales letter I wrote for a dog grooming company brought in 33 new long-term clients, resulting in over $62,000 in revenue the same year. * An email series I wrote in the internet marketing niche brought in $23,000 during a five-day promo. * One client experienced a 20% increase in sales after I rewrote their website content. * A sales letter a client paid me $250 to write has brought him over $35,000 in sales in one year. To put it briefly: If you want a sales letter that generates a massive amount of sales... webcopy so compelling readers can’t take their eyes off the page... and emails that convert like crazy, then you’ve come to the right place. Stop fumbling around in the dark playing the guessing game, changing your website, then guessing again. There are better - more effective - ways to spend your time and money... ... After all, the more time you burn trying to get it right, the more money that slips between your fingers. Let a tried-and-tested, sales producing copywriter handle your copy... it’s the smart thing to do (that’s if you’re serious about your business). "Once again Joe over delivered! I have paid 5x as much for sales letters that don't even come close to the quality of Joe's! The best copywriter on oDesk period." -- Jeff Brokaw Why You Should Hire Me To Write Your Sales Copy * I’m deadly serious about copywriting. It’s my livelihood and passion. I’ve invested both time and money into learning my craft and keeping up to date with current selling strategies. * I’ve built a rock-solid reputation on Upwork as a top copywriter, and if you think I’d jeopardize it by producing sloppy work for you, you’re crazy! (Fun fact: I’ve never had a dissatisfied client. Not one. Check my feedback.) * My skillset is not limited to writing copy. I’m also trained in creating profit-pulling sales funnels (so you can maximise the amount you make per customer), and mapping out product launches. Here’s how we’ll work together to transform your site into a profit generating machine... 1. Contact me. Send me a message here on Upwork and let me know what you need and when you need it by. I’ll slot you into my schedule and give you a completion date - typically 5 - 10 days, depending on how big the project is and my current workload. If you need a job completed urgently (within 3 days), then I can do this for a 50% surcharge... ... I charge more for urgent jobs because I have postpone other paying projects, work nights/weekends, or spend time away from my family. 2. Provide me with requisite information. I’ll need access to your product and current marketing material if you have any. If not, I’ll send you a client questionnaire that, once filled out, will provide me with everything I need to get started. 3. Send over the contract with your payment funded in escrow. 4. Relax while I take care of things. Once I’ve received the information I need, I’ll begin working. I’ll pore over what you’ve sent me, and begin researching your target audience in great detail. This includes: dissecting ads that have been previously successful, monitoring online forums where your market congregates, so I can learn the jargon they use and familiarize myself with their pain and frustrations, coming up with new ideas to grab their attention and gain their loyalty for your company. Once I’ve completed my research, I’ll begin writing your sales material. 5. First draft & final payment. I’ll send you the first draft and you’ll release my payment from escrow. My service comes with two rounds of revisions, free of charge, so this is where you’ll let me know whether you want anything tweaking. 6. Profit! Now, as my profile is so highly ranked on Upwork, I receive job invitations on a daily basis. As a result, my schedule can get very busy, so I’d urge you to contact me today if you’d like to work with me. Get in touch. Your bank account will thank you later. Joe
