Not a bad start, but I do have one observation.
This statement..."inexpensive racket stringing"...is a bit misleading, isn't it? It seems to beg the question, "compared to what?" For instance, Cyberflash is $7.50 a set, yet you advertise $25 to install it. Again, I'm not saying your prices are outrageous. My guess is you charge approx $15 for labor and you mark-up the string. My point is you might want to consider rephrasing the opening sentence under Servicing & Pricing.
