"I've employed more than 20 contractors, I believe there are three types; there are those who simply do as you ask, essentially human robots, but if you don't know exactly what you want or how to articulate it you will be sorely disappointed and left out of pocket.
Then you have the second type who believe they have the ideal combination of technical and marketing knowledge, so when you ask for some support they think they know best but you are left with something that you don't fully believe in or it takes three times longer than necessary to get it to a point you're happy and you are left exhausted.
On rare occasions you find the third type; someone like Vaggelis (SimpleRocks co-founder) who is able to quickly look inside your business, asks intelligent questions and has the ability to deliver exactly what you need first time. He is then, more importantly able to use his experience to advise you on how to increase conversions, tweaks which would've taken lots of ad spend to have worked them out yourself.
I can't recommend Vaggelis more highly. In fact once you find a contractor like him you'll never want to let him go and you will dream up new projects in order to snowball your business as you are now confident you have worked out how to spend $1 on advertising and get back break-even or better."
