I'm sure there's a few reef clubs in your area.. no? I'd check them out and see which, if any, have a club PAR meter that they loan out. You might have to be a member to borrow it, but I'm sure there would be a lot of other perks to being a member as well.
To be honest, I'd expect you to have a hard time borrowing one from anyone not local to you that could bring it over and check it for you. You're just some random person on the internet (no offense... but I mean, I am too for that matter).
"What, exactly, is the internet? Basically it is a global network exchanging digitized data in such a way that any computer, anywhere, that is equipped with a device called a 'modem', can make a noise like a duck choking on a kazoo." - Dave Barry
