Bad Credit Mortgages?

I am looking to buy a house in the next couple of months, but do not have the time to repair my credit. Does anyone know of a mortgage company willing to help out people with poor credit? I am sick of throwing money away renting.
For anyone interested in helping me, I live in Scaumburg, IL (suburb of Chicago). I also just moved up here from out of state last year (April), so my job history is not that long, and also I’m a sub-contractor, so paystubs and w2 forms are a problem. Now with all these details, anyone still think they can help me?
