2nd Lien Loan Needed - Construction Biz - $18M Rev

I'm helping a Commercial Glazing company look for a loan. $18M Revenues, -600k EBITDA last year due to a $1.8M vendor issue that is being litigated now. Total debt is $670k (220k SBA + 450k LOC).

We have one proposal from Finwise but would like to see other options. Could do AR Factor ($2M AR) or longer term loan to take out the $670k plus provide additional working capital.
