Hi, how are you doing?
Can I ask how far you've got building your directory so far, please?
If I were to work on this I'd start with a blank page and build from scratch, in raw php/mysql/html/css/js/jquery. I would find this quicker and more flexible than working within a framework, but then I am very old-school in the way I do things. Well, it depends on how complex the functionality is, so I'd like to discuss that with you, or even better, if you can show me any designs or project plans, I could quickly assess it.
This would include a basic admin system to maintain your business.
I have built web directories before, I built one years ago with the intention of covering every province in the world. Programmatically it worked fine. I have also worked on many dynamic websites including 11 years experience working for a yacht charter company as their sole programmer. Their main website was search listings, database driven, which is very similar actually.
Anyway, please check my profile/reviews and if you'd like to go the fully customised route, please send me a message and we'll agree a time to chat, or send me your design/project plan and I'll send feedback as soon as I can.
My quote and time frame ($700 total for 10 days) should cover the costs for what I think you'll need. Let's see!
