Maintaining years of blogging and having done endless work, presentations as a teacher, the search for sources and information is something necessary for my proper performance. I am Greek I live in Greece so I know exactly where to find what I want. Although I do not know exactly the purpose of your research, I believe that I can help you in your research and in the data you want to collect. Not knowing exactly the subject and how much is needed for an even result, I can not set a specific value.
Sincerely, Christina Georganoudi
