Translation from English to Japanese

I need two documents translated from English to Japanese. One is a document in Excel the other is a Microsoft Word document. The documents are for a software program. There are two stages the first stage is translation of the Excel document that needs to be submitted back. The submitted data is then entered into the software program which is then used for screen shots that will be added into the word document. The word document is a technical manual that has to be translated also. I know it sounds pretty complicated but it is not really and I will explain everything as we go through it. This will be a simple project for someone good at reading and writing Japanese and most of the project will be typing out text/data entry.
