yea i went through about a dozen freelance marketers in the last few years for our marketing biz -
www.marketmofo.com - all with the same problems. claim they can do it, accept the project, then keep giving me excuses until i do the job myself or reassign it. a majority of our problem was that most of the guys didn't want to do repetitive work, even though they accepted the work. the other problem was someone accepting the work when they didn't know exactly how to get it done.
the way i solve that problem is now i hire people that have already been doing the work for little or no money. for instance, when i needed a new tgp guy, i trolled gfy to find an affiliate that wanted to make more money for the work he was already doing. when i needed a Facebook guy, i found a popular page and sent a message to the page admin. same on Twitter, Reddit, Tumblr, etc.
back to the subject (again), there is a general laziness in the world today. not sure if it is a result of the recession, or the recession is a result of the laziness. all i know is i make a lot more money by being the guy who ISN'T a lazy fuck lol
