Looking for advanced tennis partners in the Cupertino area

Hi, I recently moved to Cupertino and I am looking for practice partners close to my level (4.5).  Most of the times I can play in the evenings (after 8pm) or weekends.

I haven't joined the Cupertino Sports Center yet but I am willing to pay the guest fee and if I can find partners eventually join - especially for the evenings having good lights is a plus.  Other possibilities are Santa Clara tennis center (Central Park), Murdoch Park in West San Jose, Fremont High in Sunnyvale
