You can save a lot on that budget in Turkey;
Antalya Geyikbayiri(about 3 euro for camping at Climbers Garden and food is cheap) for great limestone sport climbing... You should be able to find climbing partners there..
Olimpos (less than 10 pounds for B&B and dinner in a basic hut) for sports climbing and chilling out in a popular backpackers place..
Bafa Lake for superb bouldering..
Aladaglar mountain range for multi-pitch in alpine style and sports routes... try contacting Recep at www.aladaglarcamping.com for finding climbing partners there.
www.rockrun.com sells a guidebook for Antalya...
