    Normally when you hire someone on ODesk, you’re just hiring one guy. But when you hire me, you’re taping into a large reservoir of untouched potential. I am Totsean, which means I belong to a community which has been active since 1997 and which dates back to 1989. And like other Totseans I have the support and backing of creative individuals. From Starting a Business to creating custom software solution, we can handle everything. I myself have worked with Community for over 7 years and I have a vast amount of knowledge on various areas. I primarily focus on Video Editing and Creation but I am skilled when it comes to SEO, Setting up Forums, Managing forums and getting your brand name across. I have some strict working principals, I never cheat and I never scam. I have helped people for free for 7 years, from tech support to helping them deal with life problems. I don’t intend to change that, it’s just something makes me stand out. You’re not hiring an ordinary person here; you’re hiring an individual who has proven to be an effective leader and truth worthy person. If you don’t believe what I have written above than you can come and chat with me and discuss things. Remember, I am different, when I work for someone; I dedicate everything in order to get the job done. I do free samples and I do free support even after the contract ends. I am here to build a positive relationship and help people who have been scammed in the past.  less
