merchant cash advance

My husband is currently contemplating a career change. He is thinking about leaving his current law firm and joining a small local firm. In the alternative, he is also speaking with the CEO of a small local company to determine whether he might move in-house. One concern that he has about the small business is the company’s cash flow. I think he would be a lot more comfortable with the business if he knew that it could call upon a merchant cash advance, perhaps[s in the form of a line of credit, whenever it needed operating income or to access cash quickly.
