Do you need someone with awesome communication skills, a solid understanding of web design, and swell English? (Yep..."swell".) Are you a fellow entrepreneur/internet marketer who needs to customize your unique project in a way that matches your style and branding? If you answered "Yes" to any (or all) of the above, send me an interview request today. I always aim to exceed my clients' expectations, and a review of my client feedback will confirm this. I'm looking for interesting projects in the following areas (preferably in the real estate industry, but open to interesting alternatives): - light web design work/customization/consulting for real estate agents & brokers - lead generation / internet marketing consulting for real estate agents & brokers - automation consulting (I can help you get rid of time-consuming / redundant / redundant tasks so you can focus on more important things) Preferred Contracts: - $300 minimum (if flat rate) - Less than 5 hours per week (if hourly) Send an interview request today and let's see how I can make your project a smashing success! I've been designing websites, graphics, spreadsheets and software for over 17 years, over 95% from scratch. My specialty is the area having to do with "Direct Response" methods of lead generation, having studied almost every Dan Kennedy book and dozens of self-study courses over the years. I eat, breathe, sleep and dream sales and marketing. You think like an entrepreneur, and so do I...because that's almost all I've known for over a decade. I've been self-employed in some form my entire adult life. Borderline-obsessive work ethic is just another day at the office. I've gone through Tim Ferriss' "4-Hour Work Week" almost a dozen times. GAME. CHANGER. If you've read it, you know what I mean. If you haven't: read it. Real Estate Experience: - licensed residential real estate agent since 2005 - full-time real estate agent 2005-2010 - worked with investors, relocation companies - former real estate Board member + teacher Web Design And Lead Generation: I have spent the past 9 years working extensively with: - Custom landing pages/"Squeeze Pages" (many for the Real Estate niche) - AWeber + GetResponse automated email delivery services - Loan Pre-Qualification forms (designed for real estate agents + residential lenders) - Tons of form-filling processes and data capture on the web - Wordpress integration, theme customization, and theme-building - Internet Video integration - PDF/eBook generation - Fixing bugs so sites display correctly (a necessary evil) Sales & Marketing: - I've been selling enthusiastically since the age of 5 (it started with selling pencils door-to-door. I made $2.50 in 15 minutes. My mom yelled at me and made me return the money. It was on this day that my disdain for authority was born...) - I own (and actually completed) more sales, marketing, real estate investing, and real estate agent training courses than I can count (over 100 at least) - I hired a professional sales and marketing coach for approximately two years while practicing real estate, and amassed a well-rounded business education along the way - Barely old enough to vote, I spent 3 years selling telecommunications service and building sales teams I've also spent more time than I can count on: - Writing custom email campaigns - Writing eBooks and Free Reports for website give-aways - Designing custom graphics, flyers, and advertisements - Designing website elements (logos, buttons, banner graphics, backgrounds, etc) - Copy writing / sales letters (long- and short-form) Long story short: I have a strong background in the many aspects of internet-based sales and marketing, I love sales and marketing, and I'm a stickler for details. Send me an interview request today and let's see how I can be an asset to your project! I'm very familiar with the following languages and tools (if your project requires them): - HTML / PHP / CSS - Javascript / jQuery / jQuery Mobile / AJAX - Adobe Photoshop / PSD-to-HTML - MySQL databases (and website integration) - Microsoft Excel (I've designed hundreds of custom spreadsheets and 3 complete software solutions for myself and clients) If you're looking for a developer or content writer with a strong background in the finer points of sales and marketing, one with an obsession over the details, one with a thorough understanding of what it takes to generate you more business and get you more email subscribers, send me an interview request today and let's see if we're a match.
