The question with these guys is always why is this client not going to the bank?

If the answer is, "I have a bank LOC, looking for more," then you should hit up Bluevine and/or Fundbox. Rates are much higher than he's used to.

If the answer is, "I haven't tried yet," then you can make money by taking him to the right bank.
If the client is in a B2B industry, there are several other ways to do this, as well.

Please reach out to me, I have a way to help you monetize.
