Custom Script Needed to Automate Site

I? have this website that I accept job orders through, and if I don't accept the order in about 2 seconds or someone else gets the order. I'd like to be able to automate this a bit so I can get 2 or 3 orders a day. This is the html from the site i need this to work on: <[login to view URL]> I need this to do several things. 1. Auto-refresh the page about once per second. (very important) 2. When an order comes up on the page there is a yes/no check box to accept, click the yes box, then click ok on the dialog box that pops up to confirm. (very important) 3. I'd like the script to kill itself after successfully doing this 3 or 4 times (or some variable that can be changed later) if it keeps accepting orders and I end up with 20 orders I'll be screwed!
