150251 Mini CMS to update XML file.

I need a mini CMS programmed to write and read an XML file. Please see the attached document with full specs of the project. The work required is very simple. I am not looking to spend more than $100. I would like to have the solution delivered within 24 hours of awarding the project. I would be OK to extend this time slighty if required: but the time table for completion would need to be agreed before starting on the project. There is a lot more work following this project. I am looking to get one or 2 permanent PHP programmers. (Though please don't give a low bid hoping more work will be given.) Any questions, please send a PM. Thanks. OM
