You're welcome! Here's the budget option: http://www.jensonusa.com/Shimano-Deore-M615-Rear-Derailleur http://www.jensonusa.com/Bicycle-Cassettes/Shimano-HG-50-10-Speed-Cassette http://www.jensonusa.com/Shimano-HG-54-10-Speed-Chain http://www.jensonusa.com/Race-Face-Single-Ring-Chainring I believe Zee shifter has the same pull ratio as Deore ones so it should work with this deraileur but I'd double check with Jenson. This setup is what, 130 out the door plus cable and housing. I have what I listed first so no personal experience with this one, likely will be plenty good. I say mountain bikes are very cheap!
