Bridal planning and vendor tracking software

I am looking to create a unique website that is based on a melding of the concepts found at the following websites: [login to view URL] and www.bridepros.com. ? I want a website/software app that is similar, but will also automatically list all the wedding related vendors in a predetermined area of the bride, based on her zipcode. ? Is this possible? ? Vendors receive their initial listing for free, but would sign in as a member to upgrade services to additional options (much like [login to view URL]) I would like this to one website, but the site would also be able to include a blog, photos, articles. etc. ? Lastly, I would like to be able to make this planning tool at link that can be added to other sites, for fee or not, unsure yet. ## Deliverables Once I understand whether this type of site can be created, I would like to discuss the design of the site at a later date. ? This will be a membership based site for vendors, and free for brides. ? Want to be able to include affiliates on site as well.
