Well Done Works Business ideas and formation

I have recently formed a new LLC but I am totally ignorant of hire to properly build the businesses credit as quick as possible. I have just fitter matured for the first time last July I was ac year and a half before that in prison and I did 11 years. I had a great job as a utilities contractor but that would require me to move and my wife had worked for the city almost 20 years I can’t make her leave nor can I leave her.I have been without work for almost 2 months I have saved money but it will run out and I will be a back to being a space for someone else again. I am college educated but when they find it I have been in prison that long I get denied. I was convicted on fraud charges and given 13.8 years I don’t do any dumb moves without truly considering the consequences . I know a lot of people that are licensed plumbers and irrigation specialists or I have to dump trailers and could do a junk removal business. I need someone with the knowledge to help build the LLC’s credit and the experience to help decide what type of business and how to start a marketing campaign to slowly start to get jobs and form my own business.
