Does anyone know how much roto-rooter typically charges to unclog a floor drain in a basement?

My basement floor drain clogged up over the weekend, and I've been to Home Depot about three times today to buy a 50ft snake, and a few different various bottles of extremely corrosive professional grade drain cleaner, but nothing works! Seeing how it's Christmas Eve, my bank account is pretty much history exept for maybe $15. However, when I get my next paycheck, I may be able to call Roto-Rooter depending how much they typically charge for a clog like mine.
