I have a site running on PHP 5.3 right now
Our hosting company is going to switch to PHP 5.4 in 30 days.
In the meantime, I can switch back and forward from 5.3 to 5.4 for testing purpose.
I need a php specialist that can help to fix bugs that appear when switching from 5.3 to 5.4
The task should preferably be done during nighttime CET.
