It's not. Smart small and add tools/materials necessary for each project - similar to how anyone builds their workshop at home. You don't buy everything at once, you add it as you need it.
Solicit your services, such as rekeying, on Craigslist or through HOA's. I would suggest focusing on residential rekeys and installs first, personally. Large profit margins, plenty of work, and COD. Can't beat that. Heck, you might even try assisting listing agents in exchange for them handing out your card and/or referring you to new home buyers.
Good luck.
