looking for help: white shade tent

Looking to see if anyone in Austin can lend me a white canopy/ shade tent. Wanting to borrow it for a couple of weeks, or at least on a couple of occasions in the next month. I'm looking for something much like this. The removable side walls would be a bonus, too. It being white is quite important - wanting to use it to take some pictures under, so other colours will cause problems.

If you have one, or know someone that might, please leave a comment, with contact info, or send me an email. Thanks!
