Need help with wordpress and core php fixes

We are in the process of moving client sites from php 5.2.7 and 5.5. There are some anomalies that need to be addressed. Most of the work is core php, some minor tweaks on a couple of wordpress sites. The changes should take less than 8 hours work. There may be a couple of sites that will need further work, if they can't be completed within the 8 hours we'll discuss those sites separately. They are custom php applications so may require a bit more time. Need someone that can work during US Pacific time (GMT-7) to work together on it and get things done in real-time. Please only apply if you can be available during this time. If you are experienced php programmer the issues should be quick to fix. If you can start right away today that would be ideal. bid should be for 8 hours of work. thanks for your interest
