In reply to Cliff S:
Could you try Neil Gresham, pretty successful deep water soloist?
On the other hand what instruction do you think you need? Start (stick) with S0s, learn about tides, check the depth regardless of what guide tells you etc. Should be a few articles around of how to hit the water properly. If you can climb, you can dws, just be sensible insofar as any of it is sensible! Costa Blanca could be a good bet, but the south coast is plenty warm enough come the end of summer.
Good luck.
