Need a lender who can do a line of credit for a roofing company.

This needs to be fail-proof. If they do not fund construction, or aren't too favorable to construction, then don't bother.
If they only do factoring, it's a no go.

Needs $1MM ideally or more.
AR shows about $1MM over 90 days.
FICO 690+
Gross $5MM+

PM me if you can do this for sure in-house or have the lender who can get it done.
