I know that you are looking for a "trusted company", but I would suggest that you look into the reprap project. Basically what all of the Makerbots, ultimakers and all other "maker" printers are based off of (including a lot of the kickstarter projects).
Being that it will be used by an FRC team, I would assume that you have the skills necessary to build one:
http://reprap.org/wiki/Main_Page.
For $3,000 you could potentially build 3-4 printers of the quality of a makerbot. As a benefit, if it breaks, you built it, so you will know how to fix it.
It may not be somthing that you could get up and running before this build season (you could actually, but it would be a crunch). It would certainly be a great offseason project for the team.
