The Marine Corps is soliciting quotes for in-person Navy-Marine Corps Correspondence and Written Communications Training Services, to be delivered as six two-day seminars over a 12-month period—three at the Pentagon and three at MCB Quantico. The training must align with the Department of the Navy Correspondence Manual and the Marine Corps Supplemental. This is a total small business set-aside for a single firm-fixed-price purchase order awarded on a best-value basis, with technical capability and past performance weighted significantly more than price. Offerors must have active SAM.gov registration and keep pricing firm for 120 calendar days, with all travel costs included in the unit price per seminar. No budget amount is specified.
