Manual Installation Mambelfish for Mambo 4.5.2.

Install (and make work) Mambelfish over a Mambo 4.5.2. version. I currently run the english version and want to make the frontend available in dutch. I tried but have no clue of how to make it work.. It needs a manual installation I think cause it didnt work while trying to upload the zip package. I can pay 50 USD for it. Take into account that the current content is in Dutch but runs over the English lang files. The Dutch texts/menu however should be assigned to the Dutch version and the English content which I shall provide should be attached to the English version. This is quite urgent and needs to be done before wednesday. Only people that know what they are dealing with please.
