Let me just go through my check-list for the usual warning signs in bitcoin trades:

Seller is in a hurry to get bitcoin CHECK ✓
Buyer must pay first CHECK ✓
Not offering full escrow CHECK ✓
Have a perfect rating on "somewhere else" CHECK ✓
Newbie account CHECK ✓
User with negative feedback CHECK ✓

Not saying OP has bad intentions, just saying there is a lot of warning signs here.
