I try several invidual and company for some of sites. but None work as what they said. some got some boost, some totaly uselessful.
Mostly they persuade me and will try best for my site. after take my money, they are lasy, i guess they take less than 1 hour per day for my project. 
They take much time to persuade me.
I pay them
They take less time for my project after got money.
They deliver less than what they said before. i even got no respone because they are very busy, definitely not for my project. my project fail.
I am too tire to hassel for refund and more , time waste. i must do it myself or cancel it.
How to choose good one?
