Would you pay some % of the sum upfront? I don't trust to people with 2 posts, not after I got ripped here few times.
Have to talk with my designer if he's free for work, I can't do this myself, will let you know tomorrow.
I'm ready to give you an exclusive offer (probably around $1k for all designs). Going to give you work samples after my friend agrees about it. In the mean time, you can find my contact @
