The real question is what is the merchant's profitability. Top line numbers are great but if he's losing money every quarter a real balance sheet lender would kill this. By the way I believe Funding Circle can be an option on a traditional loan with monthly payments amortized.

Doing this as a RBL (Rev Based Loan) for that dollar amount will be tight, I know SFS can do it and BFS but financials will be requested and site visit amongst other things.

Best to make sure you have your ducks in a row and review the financials first to see what you really have in hand.
