We might need to tread carefully here, at least one professional has compiled such a list and, quite rightly, is very protective of it. If it looks like anyone has copied those details verbatim then the legal eagles will be making contact very soon. As long as the layout, presentation and research can be shown to be all your own work then you should be fine.
Perhaps an additional method would be to ask each and every member to submit details of the bricks and mortar shops they know about, including full name, address, contact name if any, phone number, email address and website - if applicable.
As an example, a local one is:
