You call it "your" project, yet you seem to be asking for all the work to be done for you!
So what, exactly, makes it "your" project?
What work, exactly, will you be doing to justify calling it "your" project?
If you paid someone to do it for you, then that would justify calling it "your" project - as you would have paid for it!
