This is a great starting guide. As someone that heavily researched procurements for awhile these are good off the shelf resources. It takes awhile to understand the specific language and codes (NAICS, labor codes, etc) used for each of these contracts, but after awhile they start to make some sense. I would also recommend taking a look at budget planning documents and other resources from the DoD Comptroller (https://comptroller.defense.gov/budget.aspx https://comptroller.defense.gov/budget.aspx) continue to follow-up on task orders that are available under massive "ID/IQ" or BPA contracts in the billions of dollars (these are often withheld from the public but available to the firms that won the original work, though the actual values can be found sometimes in FPDS under sub-codes. Additionally, many of these folks hold various BPA / GSA Schedule contracts and sometimes their lead officers will respond to inquiries. Example: GSA Schedule 70, MOBIS, Navy SEAPORT-E, etc. Happy hunting!
