Driving instructor recommendations

Does anyone have any recommendations for driving instructors in Southeast London? I'm in the Woolwich area.

Also, how quickly were people able to book lessons? I've tried calling a few places, but they're busy until July. I'd prefer not to wait so long.

Best of luck  when I took lessons I went with an instructor I felt comfortable with that was nice and from a well known company so I'd go with what feels rite to you. Having  driven in America for years before helped when I took my exam the examiner commented that he could tell I was an experienced driver
