Hi,
I started actively bidding on freelancer.com only recently, hence my aggressive bid to start and build my reputation. That said I have been developing websites with Joomla since 2008. I therefore have the skills and experience to deliver your project on time and on budget.
Which version of Joomla are you using by the way? 1.5? 2.5? 3.x? Could you send me a link to your existing site in order for me to get a better idea of your projects?
I understand that your main requirement is to be able to add locations dynamically without having to recreate a full page and possibly a menu for each new location. You would just add a record with the location name, address and other details in some sort of form and once saved it would appear on your site automatically. Is that correct? Would you also like a google map with all your locations displayed? I could deliver that for you.
Do not hesitate to contact me if you have further questions or if you want to provide me with additional information.
I'm available to start right now and I'm also US based which could make communication easier.
I look forward to hearing from you and start working on your project.
Best regards.
Xav.
