I'll offer this with respect to hiring a guy that needs to rent the equipment....I would be more interested in his experience level than whether he owns his own equipment. It could be the guy has worked for someone else for years, has tons of experience and is now going out on his own but lacks the finances to own his own equipment, YET....To me, it all comes down to how good the guy is and not how much he owns. IMO GET REFERENCES and check them out, no matter who you hire.
