I feel your pain. Until my current lady, who's made a great and reliable ski partner, I found most people to be flaky. I can recall several occasions, where we get to talking about skiing at a random gathering, everyone gets stoked, says they are so down for a ski trip, make commitments, dates, set a place, I get the ball rolling, and when it comes time for deposits, they all flake out..."umm, you see the thing is...", "uhh my gf can't go so I can't either", "I can't afford it anymore cuz I bought a sweet new ride I can't afford", "oh did we say February?! I thought we were talking about August", etc. etc. etc., and the list goes on, and friends won't answer their phones when you try to get confirmations. It was especially difficult for me to find people who even wanted to ski, let alone KNEW how to ski in South Texas. On the rare occasion I could find friends to go, I usually still had to ski alone because they couldn't graduate from the bunny slope. It's a very lonely feeling living near the Mexican border, and being literally the only person you know of with a real passion for skiing and the mountains. :(
People are extremely unreliable, BUT, the goods news is that you don't need them to go skiing. The vast majority of my ski trips have been solo. A great way to get in a group about your level is to take group lessons. Often times, resorts offer great deals on rental/lift tix/lesson packages. If you're lucky enough to have Southwest airlines in your area, you can score cheap tix to Denver, Seattle, PDX, etc.
I suggest staying away from the big name resorts (with a few key exceptions like Jackson Hole), hitting up the independent mountains, staying in hostels when possible or other cheap motels, hitting up the local grocer so you can pack your own lunches, and riding the bus when you can (JH's great for this!) There are cheap ways to do good ski trips if you time it right. No need for our super lame friends. Good luck!
And btw, you have tons of ski friends here on the interwebs! If you're time it right, lots of peeps here are always happy to meet up and ski with a fellow bear.
