XML Processor

We need to write an XML processor so that RS Forms on a Joomla 1.5.x Linux based site (mysql) can communicate with an API from our insurance application. Please provide your experience in developing an XML processor for Joomla / RS Forms (or another forms processor if you like). We will review your capabilities, then provide a complete API guide describing in detail how the API works. At a high-level: 1. A form displays information for the customer to complete (name, address, vehicle information, etc) - about 12 fields in total 2. Once submit is made, the transaction is submitted to our API (WSDL based) via a Post transaction. 3. We calculate a quote and return an XML stream with various information (quote, payment plans, etc) which then need to be displayed for the customer to choose a payment plan. [login to view URL] customer enters in financial information and submits the transaction via another Post transaction. 5. The API returns an XML stream with either a successful purchase or errors (i.e. card failed). We'd prefer a developer in the US, but will accept bids internationally if your english communication skills are good. We have budget and are ready to go. Thanks... Jeff...
