I'm fairly young to the business so I don't have a million contacts that'll keep the phones buzzing just yet. So I've sort of had to be creative in finding leads for jobs. You think it's tough finding demo work, try being a concrete cutter :)

There are lots of places to find leads, some are free but you have to do a fair amount of digging. As far as paid services go I've tried alot of them and none of them even came close to Reed Construction Data The trick to free leads is bookmarking. Always save what you find so you can find it again.

Not sure what size jobs you look for and where but here are some examples of different agencies I've bookmarked.

U.S. Gov't
Fedbizopps
Army Corps of Engineers
FedTeds
NASA Procurement
US Army Single Face to Industry
U.S. Navy

DOT Resources
Bid Express
International Bridge Tunnel & Turnpike Association
DOT Search Engine

I'll spare everyone the individual links to each state DOT, they are pretty easy to find especially with the DOT search engine.

Company Websites That List Their Bids
Walsh Group
Walbridge Aldinger
JE DUNN
Flour

Misc
Datatek
Port Authorities
Construction Weblinks <-- Great Resource for finding procurement sites.

Hope this was helpful!
