Simple chron job

I need a very simple chron job written, and any minor help in installing it that may be needed. I also would want to test it to make sure it functions properly before having it "go live." I need this chron job to: (1) transfer one file a day for 6 days a week from one folder on my website to another folder. For example, at a few minutes after midnight as Sunday turns into Monday, a file would be transferred from the "Monday" folder into the "Today" folder, replacing what was there. Then, the next night, a few minutes after midnight, as Monday turns into Tuesday, a file would be transferred from the "Tuesday" folder into the "today" folder, replacing what was there, and so on, through Saturday. (2) do the same thing, a folder-to-folder transfer for another set of files, also six days a week, once a day. (3) (optional, depending on price)? transfer one file every Sunday in a similar way. That's pretty much it. May I have your bid, please?
