Please, check my gigs and tell what is wrong

[mpgraph]

Hello, I beg more experienced users to tell me what I doing wrong. Since beginning (from march), I have a lot views but no customers (only one but she is my friend and she wanted to get better image but also to help me).
I compete on price, on how much you gonna get for price etc. Nothing. I know I’m doing something wrong but I don’t know. Maybe my description, maybe my skills on profile. Please tell me.
