Create three page templates for my Wordpress Blog

I require three page templates that integrate into my wordpress blog. I have a professional theme and therefore need the page templates to integrate seamlessly with my theme. The purpose of theses templates is to provide all my wigets in the side bar but only display posts from a specific category (which I can define). I need the .php template files as well as the modification of the files in my theme which interact with the template pages accordingly. I'm looking for you to tell me which files you'll require. Additionally I'd need a detailed instruction as to how I can modify the files to adjust them for a specific category ID. To bid for this project pls include the word "template" in your message. If I'm satisfied with your work I will hire you in future.
