I don't know what style or what you intend to do but as most folks on here are GNAS affiliated, I'll assume you've gone down that line?
If you're desperate to shoot, you could always try another society. Granted it may not be your thing, but it will give you somewhere to practice until you can afford the right club and society. NFAS membership is cheaper than GNAS and likewise the clubs are cheaper to join. You never know, you might find you enjoy the rough side of the sport more
Check out the clubs section of the NFAS to see if you have one in your area.
