You might want to give Ameriflight a call anyway, I believe they have some kind of a "Time builder" program. My best mate flies for them and tells me he frequently gets right seaters even though most of their aircraft are single pilot.
I'm not sure how the program works, and wether or not you have to pay, but it is probably worth looking into since you only the need the night experience.
Once you meet the minimums they would be a good outfit to start out with. My friend started with them in the Lance, moved to the Navajo in 3 months and the Beech 99 three months after that, he now flies the Metro and 1900 for them.

I just remembered, another mate of mine started out as an FO flying Beech 99\'s and 1900\'s for an outfit called Alpine Air based in Provo, UT.
They operate around Utah, Montana and Idaho, he said they treated him well and the pay once you made Captain was around $50,000.
