e107 expert needed to convert my Greek Iso mysql db to utf-8

Hello, i need an expert in Mysql and probably php. We have a non-profit web site that runs on e107 ([login to view URL]) CMS version 0,7,23. So far we have managed to work on ISO encoding but it's time to swift... Tasks needed to be done : 1. Database conversion from ISO to utf-8. At this time our database structure is like this : [login to view URL] I have attached a file with our current database sctructure. It is in latin1-sweedish, which is not Good. I need all the database to be converted to utf-8 and be stored in mysql as utf-8. 2. The websites language files are in iso greek encoding, so they need to be converted (with save as... through a good editor) as utf-8. 3. An upgrade to the latest version of e107 is required. 4. The chatbox_menu has problems when writing in Greek. We need it to be modified so as to display Greek correctly. The project has very low budget, so i need someone who knows what to do and not wasting his time. Maybe it's good if someone has worked with e107 before.
