What is the best way to start up a home improvement business without all the credentials? Ways to get the word out….etc?

trying to start a small home improvement business and no one knows whether or not i have to have a contractors license or whether i just need to have insurance. i think i might need at least a class C license but i’m not sure. any advise/answers would be greatly appreciated. Thank you

I want my home improvement business to be legit, how do I get a license, bonded and insured in Wisconsin?

Starting an home improvement business is what i really want to do in life. I just do not know the first thing to do. I need some steps to get me started. What do I do??

When will the home Improvement business come back?
I had to take a job Due to the slow down and I now work in sales selling printing supplies and hate it . The money is just OK but my Heart is just not in it. I would Rather put on jeans and tee shirt
vs Suite. I gained weight and now very unhappy. I am 54 what can I do
working for a company is not cracked up to all they say.
