I don't think anyone would be interested in going first on a trade with a Newbie here. Even some trusted traders cannot convince their customers to go first without an escrow, it's logical thinking.
Sounds cool, but how are you going to ensure me this works for both sides (I deposit BTC and receive the fiat) and not just one-sided (I deposit BTC and nothing comes back in return)? I'm sure you wouldn't trust me if I was to ask you to go first..

"I can even accept
MM for first few orders as my capital is low atm" Just to build my trust for now.
Depends how much it is, say if you send $100 in BTC
You would get $90 after my fee
Then minus 2.5% + $5 WU fee
You would receive total $80+/- $1/2
