In reply to Ella D:
Rich Mayfield at the Orange House springs to mind for me too - it's a lovely and friendly place to spend some time, and the climbing in the area is excellent for both single and multipitch. If you stay somewhere like the Orange House though, if you're already competently leading trad multipitch, you could easily pick up some new friends and partners to climb with unguided too.
No idea about companies or guides in the area, but I really enjoyed Orpierre a few years ago and October is probably a good time of year to go. Again good options for single and multipitch, and no need for a vehicle to access a lot of it.
