107351 data record delivery online

I am looking for someone who can create a script that can handle delivering record entries to users. Essentially, one master record of all entries will be uploaded to a server and users will 'buy' a certain number of records. System must be able to 'count' how many records the user wants delivered, and then compile them into a downloadable which is then made available to the user. Records must be able to be sorted based on user input criteria, on a number of fields in the data. Data may contain up to 20 or more fields. Records may only be delivered ONCE - so each user gets unique records each time a purchase is made. Initial data format of master records can be made available in XML or XLS file for you to work with. Downloaded records must be made available in standard CSV format. I need the script to be able to handle all the above tasks, and also to be able to accept NEW master records each month or period determined by the client. Must be able to interface with [login to view URL] and existing CRM system we are using (Manage Pro by InfusionSoft) I need a complete solution here, from record sorting, to unique record delivery output in CSV format - unique for each user. Please bid accordingly. Blanket bids ignored. Post examples of data work to be considered. Provide logins were needed. Thank you.
