Try Portsmouth boat club. portsmouthboatclub dot org. (I don't have enough posts to do links yet).
As to boat ramps there are several in Virginia Beach, the lynnhaven inlet should be good very shallow though. There is a ramp just off Shore Drive at the lesner bridge. There is also Back bay again in VB
The cove might also be something you might be interested in. It is by the high rise bridge on I64 in Chesapeake.
Then you also have the Elizabeth river both east and west branches, which right on your doorstep.
If you don't mind traveling a bit there is North Carolina 45 min to an hour drive. There you have the sound to sail on. Also very shallow in some places.
Hope this helps
