Need Mixing Services

Hello. I have a sort of a silly question. I'm a producer working on my wife's gospel album, but I don't have a treated room to properly mix these tracks. So my question is, is there a such thing as "touch ups"? For example, if I mix the album, could I send you the stems and you adjust/correct what I've done? Once again, I can't accurately judge the mix being that I don't have an acoustically treated space for mixing. However, I am confident in the fact that I can get it pretty close. Is this possible?
