More specifically, Room Checks.

We currently use a paper form to keep track of our Room Checks under our SLA.
Our SLA states that we will check an IT room every 2 weeks.
So I wish to setup a form on our new Sharepoint whereby users enter the Helpdesk reference number into a box once it is cleared, and it marks the flag on the field as done. If the time since the last check is over 2 weeks, it highlights them. Perhaps in an area at the top marked "Outstanding Room Checks" and thier assigned technician.

I have absolutely no Sharepoint or Infopath training, so i'm an absolute newbie. This may even be outside the possibility of SP. I have been trying the almighty oracle that is google, but not knowing how to word the query, couldn't yield any good results.

Thanks in advance.
