If I can't find a way to save you as much on your build cost or marketing & operational systems... as the cost of consultation - it's on me. (no charge) > But, wait there's MORE! (lol) In-depth SEO audit & reports of you and you competitors, Marketing + Operations Analysis, Coaching from concept through launch+, plus many other dreadfully boring things nobody but me seems to actually like doing. Frustrated and need intelligent help with the abundance of techie tasks holding you back and eating up time? Making sense of conversion rates, online behavioral marketing, funnels, landing pages, email campaigns, CRMs, social media, memberships, HTML this, CSS that... [What is a cPanel again?] the list goes on and it's mind numbing at best. You need to work on your business. Let me take a load off your shoulders. HAVE SOMETHING MORE ADVANCED IN MIND? Throw me a curve. Do 5 figure months bore you to death? Do you currently gross more than $1m/yr ? Let's cut the small talk and play ball.

TURN 'WORK' INTO PASSION & PLAY Do you want the freedom to spend more time with family and friends? Travel the world? Live spontaneously? Imagine walking the great Wall of China, Swimming in Bora Bora, Climbing a Mayan Temple, or Leaning Tower of Pisa. Perhaps go snorkeling at the Great Barrier Reef or simply watch the sun set from your favorite resort 1/2 the year? I have done all of this and much more, and I can help YOU realize these types of dreams too! It begins with a relaxed mind and a well oiled online business. My experiences which span 24 years in business and 30+ years online are concentrated on community building, business processes, marketing and general analysis. These skills have been exercised across several industries including: Retail, eCommerce, Hospitality, Fitness,Travel, Real Estate, Charities and Online Community Development. I will work closely with you to understand your exact needs, goals and ambitions. Together, we will discuss the situation and brainstorm potential scenarios until we narrow the field to a working solution. If you require ongoing support, I will be there for you when the time comes to review progress and suggest/implement tweaks as your path or details change. Helping people achieve business goals based on their desired lifestyle has become a passion. I have personally earned a lifestyle which has taken me around the world and have experienced things most will only see in a magazine or on television. It is my purpose and goal to help others create a situation for themselves, where they too have this opportunity to live out loud. During the interview process, I will listen carefully to your concerns and weigh all options before moving forward. I am not looking for a 'job' as much as long term partners. If you have a great idea, a solid team and sufficient finances to back it up, but are lacking a piece of the puzzle... I may be able to help you. As much as you will interview me, I will interview the situation and will only accept contracts where I believe the client will ultimately be successful. My schedule is purposefully left fluid as much as possible to accommodate client deadlines, the beach and sanity. We are most productive when we are energetic and full of life. I can help you create a similar situation for yourself. Due to confidentiality reasons, previous business relationships will not be displayed on a public profile. Please do not ask for samples of business, marketing or strategy plans as these files are critical to the survival of a company, could violate NDA's, unduly expose IP rights and open the doors for legal action. You should expect the same level of respect and confidentiality from me. If you are serious about taking the next step. If you honestly have a burning desire and are ready to do whatever it takes... we need to talk.

    Perl programmer and systems administrator

    Andorra - Last active: 1 day ago - Tests: 2

    I've been either writing perl or administering systems (or both) for the past 30 years. I've used perl both for administration and large web projects. During that time I've worked for many of London's banks and telecoms companies. I was head of server support for Credit Suisse, undertook desktop refresh project for Merrill Lynch and server architect for Sportal, CTO of FDD, and have held a wide range of senior admin or development roles. I've also been involved with many startups (3 of them my own). I'm creative, understand business imperatives and finances, and have undertaken technical marketing and sales. Recently I've written flooting.com a site devoted to reuse in OO Perl. It's live now, feel free to take a look. I now live in Andorra with my wife and children. I'm quite keen to keep my skills current. If you need someone to quickly grasp what you need and hit the ground running, I may be the right guy for you.
