IP Redirection for Joomla Website

Hello, I want to have an IP redirection module for my website [login to view URL] and www.dentalpeople.eu. I have posted this project earlier. One candidate did his best but unfortunately there should be some changes on the server and my hosting company didnt do it. After that there was another guy, i will not mention his name, promised me to deliver it on saturday morning and he disappeared. So I have to post this project again and please keep it in de mind that there is no any changes allowed on the server. Regards, Faro
