Craigslist in your vacinity would be my recommendation.
Lots of strange folks in Craigslist. But lots of tortoises needing homes too.
Post a WANTED ad for a RT.
I adopted both of my Russians from oiur local humane society. I was trying to locate an eqyptian but these came available (2 a year apart) so jow I don't have room for an Eqyptian, oh well, these guys needed homes.
You might check and put your name in at your local humane society.
