#1 Spend $20k on leads to broker deals and understanding how MCA underwriting works and what's a good deal, what's a bad deal
#2 Start syndicating in the good deals [you are essentially funding...]
#3 Use a funder's platform and/or start white-labeling
#4a Get LendSAAS (or similar) and investors and hire underwriters
#4b Figure out how to get the deals in the door

I think that's pretty concise, but can be expanded on. There's also more ways in if you had more money.
