Asking for advice on gov't contracts

i have been contacted about bidding government jobs, looking for advice about it. I want to go to Florida and Texas and get in on the clean up. But I don't honestly know how to bid these jobs. Proof that they are real. I have been sent a contract to be a sub with another company. Any advice will be appreaciated, I have a small excavating company in Missouri. Eager to get out there and just do more I have good work here just figure winter is almost here and ready to get more going.
