Alternatives to SBA Loans

Hello fellow searchers,

Anyone have experience working with "Loan Consultants" or "Loan Advisors" who can help navigate and assess financing options outside of SBA?

I know up market there are often M&A Advisors or I-Bankers. This would be evaluating businesses in the $1M to $5 M Rev range.

Seem to be a ton of SBA-specialized advisors for searchers, curious what else may be out there.
