Hi there!
I can complete this PHP script for you in about 5 working days. Fetching and parsing the XML file, and then storing it in the DB (after table creation) are common tasks, so I expect this to be a pretty straight forward project with no complications.
I have vast experience as a web developer and programmer, more than 7 years working with companies like Credomatic, LLBean, Buzroll and others.
You can be very confident that I will deliver this script on time, with high quality coding, and at a fair price.
