You need to prove that you are legit(Copper membership, screenshots etc) in order to attract the attention of legit users. Otherwise, I don't see how anyone would be interested in what you are trying to sell here.
Both copper membership and screenshot really means nothing. If OP is serious then he has to lay out all the details in s topic. Then when interested users will show interest then after finalizing the deal escrow whatever the payment will be.
Assuming travelling and all the stuffs wil be paid by the user. This won't be an easy management but at least the party who will accept the deal will know that their time is not going to waste.
