In reply to eddie6655:
If you have done no research into the costs of running a shop of any sort before planning to do it, don't.
You first need to find somewhere that has climbing near, no competition locally and then be prepared to work 7 days a week for sod all for a year or two to maybe start making some money.
Don't forget, people do not NEED gear. They may want it but it is not a need.
Now find a niche market that nobody else is doing and you could be in with a chance.
Forget you are a climber, you will become a shopkeeper with some knowlege of some of the gear, and unable to carry on your hobby unless rich
