I don't want to seem rude here.
But from the questions you are asking now, if you continue with your timeline, you are sure to have problems.
You seem really unprepared to try to be up and running in two weeks.
Have you looked over the cch2o site muddy referred you too?
Have you determined a system that looks like something you could work with?
Have you looked over the parts lists of any of the systems you like or could work with?
Seems like a big investment to rush into.
I just hate to see what looks like the beginning of months of frustration.
