We have a VERY custom installation of 184.108.40.206. We need to upgrade to the latest stable version. Possibly version 1.6 CE once it is available and stable for a couple weeks.
There are numerous extensions installed and some of the CORE code HAS been changed.
What other info do you need from me in order to give a quote?
If you cannot successfully upgrade Magento, then payment will not be made to you.
