XP Embedded thin client

I require the development of XP Embedded software configured for a Thin Client to be placed in a retail store. The project is a test and will probably be expanded to include more features, Here are some the details. This application will require Microsoft Internet Explorer, mozilla firefox or equilivent browser software, Media Player, including drivers such as active x etc. to view all web sites. Acrobat for pdf's, IBM Client Access for the IBM AS400 or equilivent 5250 emulation program. Printer driver for Lexmark Laser printer(to be determined) I will required access for all network configurations. I will also need access to a DOS box to set up my networks' persistant static route. Development is for an X86 system AMD processor that will run @ 400 Mhz. Provide set up instructions and installer to put the programs onto IDE or compact flash. The thin client will be placed in a semi-public place so I will need to block some web sites. I will require a copy of all source code. Please also indicate your preferences for testing the software to ensure that all features work
