PHP script (or module) required for Joomla integration

I am in need of a php script which I can integrate into a joomla website (perhaps a joomla module?). The PHP script is basically a dynamic form which will send the information to a 3rd party (affiliate) website and then receive data back (XML)which needs to be displayed. I have a list of the URL’s where post data from the form needs to be posted to generate an XML file which then needs to be parsed into a style sheet. This will be almost identical to [login to view URL] but in PHP of course. I have all the field names required etc. This will form a small part of a much bigger site so there is potential for lots of work for a good programmer in the future. I also have the ASP scripts available for this - so the right person may just be able to translate these scripts to php? There are common variables to be passed for each of the comparisons such as affiliate number, key etc… the list of common variables will be available to you. You have the option to create an XML file on the affiliate server or return the results as XML via server transfer. This option is controlled by the variable: return_xml. I will send a list of all the variables and example of the script in action to those that bid. If you need any further details please let me know. Kind Regards and thank you for bidding.
