Magento/Cloud Hosting/PHP Expert Required

Hi, I am looking for an expert that is skilled in using Magento, PHP and Cloud Hosting. Please do not bid if you are not skilled in those areas. I am willing to pay ONLY if you can fix this issue and get my website working again. I have a Magento website and 3 sub stores that stopped working 2 nights ago. I contacted the hosting company as it was on a cloud hosting package with them. They have emailed me and told me that there was a disk error with the cloud hosting instance. He has set up a new instance and he also set up a new installation of Magento 1.7. The new system configurations is with CentOS 6.5 x64, Apache 2.2, PHP 5.5 and MySQL 5.5. Basically, he said that it looks like a PHP error may have caused the crash. He has the old website files in a separate folder now and also the old database has been imported to the new database. However, an error is preventing this website from showing. I need an expert that can fix this issue and I have a budget of USD 70 so please stay within that. Please bid early!
