Place to get my gun working?

[i wish]

For the life of me I have not been able to get my gun to shoot. I don't wanna buy a Tippmann!

I bought a brand new X-valve, and a Ninja SHP tank.

I've tinkered and adjusted but it just won't go. I've been sitting on this thing for about 8 months and really want to get out there.

Is there a shop I can mail it to and get it fixed up?

I've given up trying to do this myself.

Please help!
