Post a pic here if you can, hard to say much without seeing it.
You might also just post a local craigslist ad for it, include a pic, say what it needs, say $50/offer in the ad and see what happens.
Now, with that said, if I saw that it needs
a new seat,tires, tubes, getting the rims straightened, brake pads, and the left pedal?
,
I'd think seat = $5-$50, tires = $25-$50/pair, tubes = $10/pair, bent rim = $0-$50, brakes pads = $5-$15, left pedal = $15=$30/pair, giving me a $60-$205 doing my own labor and not counting any spare parts I had laying around and not counting any deal or discount I could get with a relationship to an LBS.
Or, if you are willing to just junk it out then throw the local cycling community a bone and put it on the curb with a free sign on it, if it isn't gone in a day then put up a free craigslist ad with a pic and it will probably be gone within 2 hours if you're in an active area. I did that with an old propane BBQ, sat for a day on the curb with a free sign, still there when I got home from work, posted a quick CL free ad with some pics, it was gone before I went to bed so I put up a "thanks, it's gone" on the CL ad I posted.
Just the reality of stuff, sorry if this sounds gruff, hope whatever you do works out for you.
ps, where in the world are you approximately located? If you're near Milwaukee WI I'll swing by tonight and pick it up from you, I'll even throw in a 20oz bottle of soda.
