This is what I do when I want to see a provider for the first time.
I look at are the ads usually today's and yesterday's. I look for signs of intelligence when the ad was being written.
Pictures are second on my list. I like certain types and don't care if they are professionally taken or not. I need the picture to show their body type and a face pic even if partially obscured is preferred.
I then look at reviews, showcase, or website to look at price, menu items and ROS. Certain menu items are a must for me; if they are not offered then I won't consider that provider.
Negative reviews are a must read. I take into account the author and the ROS of the negative review as well as the comments into consideration before deciding whether to take that provider off the list.
Lastly I look at posting of providers and postings about the provider. You can tell alot about a provider's persona by their postings.
