122122 Application update w/some ajax

I have a client that has an online PHP secure application with SSL to manage his lawyer firm. Lawyers, clients and agents can work with this application to perform a series of actions. Laywers interact with clients and agents that partnered with him, adding new files, searching clients, updating content for clients, adding new accounts, managing client's properties and accounts, etc. We want to upgrade this PHP application by adding some new features and fixing some problems we have with it. The application works now in 2 languages, but we'd like it to work in 3 languages, but I don't think it was created in such a way that it allows for adding/removing languages easily, so we'd need to add this option. We want both changes in features and in layout and appearance and add some AJAX functions to it. All work needed is explained in attached word document. Application is already coded, but we don't know if you'll need to remake it from scratch in order to apply new layout and some AJAX. Database is already created together with application, we'd need to import all this data for the new update and start using it after installation in the domain. Please let me know about it and your bid to have all changes we need for this application. Apply only if you are sure you can do this. I'll send link to those that match my criteria. Please read the attached document to know project's details Kind regards
