Add page template with sidebar to existing theme.

I am developing the site www.romebdsmconference.com. And I need a few small changes: 1) I want to add a page template that has a sidebar (on the right, on the left or both) to the actual page template. The theme is TYLER by [login to view URL] and they already have an option for article pages. Example of actual page: [login to view URL] Example of article page: [login to view URL] But I'm not happy with that template with the sidebar I need to have ane page template with a right sidebar containing banners (width 120px) and I want the sidebar column to be of the same width of the banners (or a few pixel wider). The overall width of the page has to be the same as in the single column template. 2) I also need to fix the way the language selector shows in the top horizontal menu (it's been created with the WPML plugin) since when choosing the dropdown menu, it shows only the first line, as the second line is hidden behind the main image. The other menu items that have a drop down list show correctly. The widgets that creates the dropdown menu works correctly in other areas of the page (ie the footer), but for some unknown reason is like hidden behind the main image, so that you can't actually see it. I need it to be right on the left of the REGISTER button. The language selector should have the same look and feel as the other menu items. I have simply worked around the problem having only the two flags put horizontally. this works, but is not the best solution for me. 3) I need to be able to freely arrange the listing of the sponsor categories (now it's alphabetical... which means that instead of Platinum-Gold-Silver-Bronze-Media partner now I would have something like Bronze-Gold-Media partner-Platinum-Silver. There should be some plugin already out there able to do this.I just need to implement it for the Sponsors' categories. PLEASE NOTE: Max Budget for this project: 50 Eur.
