Just an FYI ...
I routinely work with the Federal government.
Billing rates for long term "standard" tech skills are $80/hr - like java developers
Billing rates for specialty consultants like me are typically $125/hr.
Billing rates for top-end software products (ie, SAP, etc) can easily run $300/hr.
This is the discounted rate because the GSA is one tough SOB of a negotiator. The rate on the open market - typically to large corporations - is 20 to 40% more. It is not unusual for my skills to go $200/hr.
That said - $7500 at $80/hr only gets you 93.75 hours. That's like one week of actual work, another week of planning/approvals, and half week waiting for the god damn union guys to install Textpad on your machine so you can code up some PHP (which has to be coded in Textpad due to security requirements - I shit you not).
