Creloaded 6.3 test Site needs depreciated code updated to work on php 5.5

I have made a copy of our main CRE Loaded Professional B2B v6.3.3 with patch:3 at revision:1847 site onto our new php 5.5 server and need an experienced Cre loaded programmer to update the depreciated code and any other issues sorted to get the test site ready and fully working on PHP 5.5. You will need to update all of the depreciated code and get the site ready for production use. There may also be a few configuration errors that need to be sorted which need to be set because its a test site. The site is running and the admin seems to be perfect. The site has been modified over the years so please be aware of this before quoting. As i said before this is a test site so it can be worked on without pressure. Some of the errors that are present currently are shown below. There are more and all need to be fixed as part of the quote. Basically the site needs to be got ready to go into full service on PHP 5.5.34 It is currently working perfect on our other server PHP 5.2.17 and is live.
