Flooring business startup

My husband is a Vinyl Installer and had a very successful business in the past but due to the breakdown of his first marriage he lost the business and the home he owned. Since then he has been working for other companies but his heart is set on beginning his own small business again. I know I am asking for a large sum of money but i can guarantee that my husband will succeed in his start up and that the loan will be paid back very quickly. He knows the industry and is an incredible tradesman who is just not getting the appreciation he deserves from the companies he sub contracts for. I hope someone is willing to help.
