This info in this order:
- photos (very important!!)
- rates (very important!!)
- contact info (very important!!)
- stats (kinda important!!)
- general location of closest intersection (important for me at least, maybe not for others)
- schedule (important for me at least, maybe not for others)
- list of services (nice to have, but not required)
- links to reviews (nice to have, but not required)
I find schedule and location important, if only because I'm usually pretty busy, and so I can only "settle" for hobbying at very specific times and in specific parts of town. So, if I can't tell that someone is even accessible at the time and place that I'm at, then I won't even bother contacting them.
