I am a brand new painting company owner. I need to learn the inside of the business after being labor for so long. How do I go about bidding on a job with no references? Also, I have worked in construction for a few years and want to implement that

I have been on my own for 2 years now and have recently run into a problem with finishing exteriors. Things seem to get out of hand and I don’t know how to get back on track, anybody like that?
