Tammie,
If you are interested, you can get fully equipped and set up for less than $50 outlay, and be able to provide this service in a hotel incall situation.
http://nuru-guru.com/ is a site that has all the products you need, as well as instructional videos.
They sell the nuru sheets/bed protect for $40 and you can get the gel for as little as $5 there.
Only one of the local ladies advertises NURU (ChelseaBean) There are several ladies that visit Austin that have advertised it.
A search of "nuru" in Austin forum and in Killeen/Waco/ BCS forums will give you some insight into the demand and the limited availability.
The website is worth a view, IMO.
Respectfully,
OldSarge
