Help me and car dealers.

HELLO peoples of world. Im 26 years old husband, father and pack leader from Finland. I work as electrician, but i have issues with my back and i know i cant do this for life. So i have been thinking what i can and should do to earn living for my family. Few years ago i run into detailing car's as hobby. I did detail car's for local car dealears, and for friends. Some pics added.

FRIEND works for car dealer, and he told me that big issue for them are stone chips in hoods and around car. To fix them (what customer usually wants) they need to take car to the painter and its off from sale for a week or even more, and it cost around 400-1200€ from companys pocket. And because of this smaller dealerships barely stand up.

IN MY BUSINESS IDEA i can do this for dealerships and other customers more than 70% cheaper. Dealerships dont need to take car anywhere cause i will do it at their shop, and i can make it in 20-60min. This is called SPR technique that is not familiar to dealerships or any other customers.

To do this i need funding for my company, i know where i can educate myself, and buy everything i need. I need to build up company, and look professional. I need website, business cards, marketing, someone to do billing, and all other stuff. I have tried to save money from salary, but my problem is that im only one who work in my family, cause i have 11 months old daughter so my wife is with her, and this is why we live from salary to salary. For 8 months i have tried to get loan from bank, but in this financial situation they are not giving a dime for startups.

READY. I have everything ready. I know where to get education, and all equipments i need. I know where i will buy website, and i have vision for that. I know how my business cards will look, but i dont have money for that. Help me to get my business skyrocket, and lets help car dealerships to survive.
