Unfortunately, there is little for your level out there on the net, except for maybe tennisplayer.net, which costs $99/year, and hi-techtennis. com, which costs $50/yr or $15/mo--give this a shot, they're really good on modern stroke production. The kid who does fuzzy yellow balls doesn't play much better than you, so his site is a waste. You may find something useful at tennisone.com. A better way would be to get 4-5 other guys together and pay a real coach to run strategy related drills like what players do at performance centers like Hopman's. 4-6 guys splitting a coaches one hour fee has to be doable. If you want exposure, enter a few sectional events. Enter the weaker ones to get a few wins under your belt. When you play a competitive match, get your opponent's contact number and workout. That's how it"s done. Age group tourneys are easier and less intense physically, but there can be more BS on-court.
