I have a certain budget for converting an existing web app to PHP
The (old) app itself is written mostly in Delphi and it's in prooduction (ask me for a demo of the web app)
I don't expect that the existing app will be completely converted, most parts will be reused (like charst creation) and remastered and integrated by us.
It is important that final app must include and can interact with jQuery, must use Templates (already have a template) with Smarty (for web design) and can be localized (multilanguage with gettext). Must be Ajax intensive.
Hge part og the app will be based on OpenLayers and use maps form OpenStreeMaps, Bing,, Yahoo.
The app is using an existing FIREBIRD DBs of about 6Gb and millions od measures,
We prefer to be used a middle layer DB management like ADODB or something.
Must be scalable (many users connected simultaneously), every users has a login credential with appropriate access rights.
Database schema is ready.
3rd components can be used and suggested, we are open to buy also.
If you are interested, I can give further detailed informations.
