If you have a car (or are willing to rent one with some other newhires) you can try either Pilot Crash Pads with Blocked INN or LUVsuites

Blocked Inn is a house on the east fringe of the Stapleton East neighborhood, $275/month, and luvsuites is a $38/night deal, still about half of what the Staybridge Suites next to the GO costs.

Congrats on joining F9!
