How Are You Getting Sales/Leads?

Good day all, I am a Disabled Military Veteran and can't drive because of that. I am really trying to push getting clients and I am assuming I need to be going door to door (business to business) in person, but if I go that route I need to do this very effectively to avoid high costs of ubers (public transportation not really an option where I am). How are you all going about getting new clients and what types of businesses would you suggest going after for getting your first few clients?

Are all even doing in person sales, and what would you say your process is like. Would also like to know how are you targeting your ideal client so that I can see if I can apply to mine. I am offering the Microsoft products as well as maintenance services for those. My ideal target would be small businesses and maybe nonprofits (but would be willing to see if I should switch to a different target market to start if something else would give me a higher return at least starting out until I can afford to switch back to small businesses perhaps).

For anyone that can provide insights on here or through DM, thank you very much in advance.
