Create or upgrade "Thank You" page and create 301 redirect.

I need someone who can create new "Thank You" page using PHP, like, [login to view URL] Thank you page I have now, is HTML, and PHP code won't run there. Also you will have to program that I can get order value on thank you page. High skills needed, because it is not any commerce platform like Magento or something, it is self made from zero. Also need to remove "www." to our domain and create permanent 301 redirect. Details will explain our SEO manager. We have much more tasks on this page, so skilled programmers will receive repeated offer to work with us. Copy/paste bids will be not taken as bids.
