Set of ASP .net pages to send XML commands to a socket

Hi, I need a set of ASP .net web pages building to first authenticate a user against MS Active Directory (an example can be provided) and then using the AD username retrieve some data from an account system by sending XML with an MD4 HASH and CHECKSUM to a socket. An example set of .aspx pages and compiled dll's doing similar transactions via XML can be provided but the source is not available. Several configuration settings for these pages will be held in a configuration file outside of the website directory structure. Once logged in the retrieved data will be : User Details (Name, email etc), Purse and Balance Details (Normally two purses will exist, Business and Personal) and Tag Details (These are used to identify users on devices, ie. Username and Password, Smartcard and PIN) Once this data is retrieved a menu should give the user the option to change their Password or PIN Number for all TAGs (configurable to accept only numeric or Alphanumeric and configurable to hold a minimum length), change the Password or PIN configurable to accept only numeric or Alphanumeric and configurable to hold a minimum length) for individual TAGs and an option to transfer some or all of their balance to a user or number of users. The options available should be configurable in the configuration file. The option to change their Password or PIN Number for all TAGs will prompt the user for a new Password or PIN and ask them to retype this for verification. Depending on the configuration this could be either numeric only or alphanumeric and may also have a minimum length. Once submitted the page will send a command in XML to the socket for each tag, details of these commands will be provided. A result will be returned for each command which should be returned to the user in a friendly format ie. Successful or Error. The option to change their Password or PIN for an individual TAG is the same but the command should only be submitted for the relevant TAG. The final option is slightly more complex, this option will allow a user to transfer some or all of their business balance to other users. This will need to ask the user if they wish to add a set amount ie. $5 to a users or list of users purses or is they wish to top up their purses to a set amount ie. $100. This will then need to retrieve the purse information for the user or list of users to ensure that this logged in user has sufficient funds, once validated thee system will need to issue a REVALUE command to add the necessary funds for every user and then a SALE command to debit the funds from the logged in user. Once performed the user details should be retrieved again the reflect the new balance. Details of all commands will be provided along with a C example of how the MD4 HASH and CHECKSUM is calculated. Remote desktop access to a server with all of the server applications installed for testing and a GUI tool for testing XML commands will also be provided. Mock ups of all of the screen will be available. The pages should be simple so that they can be embedded into a site via iFrames. The budget for this project is $750 and I would hope to see the pages delivered within a week. Happy to use milestones payments. Regards Andy
