My company publishes a magazine for homeowners of expensive communities around the US, and we sell advertising space in it to small businesses. We are now looking to expand from the magazine and do similar We are looking for a website that we can put our advertisers in and allow users to search different industries in different locations to find our advertisers' businesses.
We will need to be able to mass upload businesses quickly and also allow our advertisers to access their business info to make any changes that they'd like.
For a good idea of what we are looking for, see homeprosguide.com. This is very similar to what we will need but with a few changes.
