Easily solved with a good deposit. Alternatively you could contact one of the party keg suppliers to see if they will source one for you but I reckon it will cost more. Either way you need gas/regulator if you don't have one as well as the fitting to dispense.
Pubs sometimes do sell kegs I have heard so maybe have a word with a friendly publican.

I doubt any Craft Beer producer would refuse to sell kegs for parties, the real issue is with the equipment-Tap, Gas & Cooler.
A couple of emails might be a good start.
