I used KiltRental.com aka http://kilt4hire.com/ and worked with Colleen a couple of years ago.

I was so happy with the low-key, but prompt service and kilt package that I ended up wanting to act on my long-time desire to buy a kilt, joined XMarks, got some great advice, and now have a 16oz wool and two pv kilts and am looking to add another wool kilt to the closet.

Note that kiltrental.com is the older site and is not well designed. I used it as a guide, then email and the phone to actually order. The kilt4hire site is more usable.
