Open contracts in Quston Contracting LLC's NAICS codes
325 open federal opportunities on SAM.gov use one of Quston Contracting LLC's NAICS codes and may be open to it: no set-aside, or, in the codes it is registered small under, a small business set-aside or one for a status it reports about itself on SAM.gov (women-owned (WOSB)). Here are a few, those in its primary code first, then those in California, then the soonest due.
Confirm eligibility first. Quston Contracting LLC's women-owned (WOSB) status is self-reported on SAM.gov, and this page can't confirm an SBA certification for it, so set-asides for it may be relevant but may not be open to it: WOSB and EDWOSB set-asides need SBA WOSB program certification. SBA's Small Business Search shows a firm's current certifications.
