Website Editing plus 1 new page

I need the following to be done on my website: 1) Edit/Re-align fonts and re-draw all border linings on about 30 internal pages. 2) Make "announcements" page editable. 3) Add a left sidebar on all the internal pages (including "announcements" page). 4) Create a new page for "promo materials" and make this page editable. Notes: 1) Don’t need to add additional graphics. 2) All borders on internal pages need to be standardized.
