Glad you found a solution! Just wanted to provide some input for the future - CNA's Western Surety program is a great option for insurance agents. They'll do all bonds up to $500,000 at a 3% rate, based solely on contractor's credit. Most SBA bonds are smaller bonds of this size, so this works out well.
If you do need any larger bonds in the future you will probably need to go through a full time bond agent. We've been in the business for over 25 years, and pay a 30% commission on all bond referrals. If you have any future bonding needs feel free to reach out at Matt at SuretyBondProfessionals dot com
