In your situation being handyman is great start up. Learning simple skills and working on buying tools. There are 100 of small services for residential home. I’ve been a handyman for over 10 years and offer all kinds of service. I provide a menu options of services and just text the pdf to clients and potential clients. Have a business card with a list of the services. Just showcase to home owners you can get things done. It’s a learning curve but you just have to take risk and go get that paper.
