Redesigned second column?

Dear support team, dear Ben

I’m very fond of the theme TRACKS, but would however like to adjust it (more than I have already done).

What I need is a second, relatively slim left column where only some posts go. I have purchased the two-column fearure, but didn’t like the look if it, and I need something else.

I would like to maintain the one-column look form primary-posts, but then have a slim left column – with another design (font, background etc) – that only shows posts in a predefined category.

I use Tracks for a blogg with restaurant reviews, and with an extra, slim column to the left I could have the main thing – the reviews – in the large column, and then have small posts with eg foodie-news in the slim left-column.

I assume this is more than can be handled by adding two lines of code, would t be possible to pay you to code it for me, could you recommend somewhere good to go – and what do you think would be the price (not exactly, just about)?

Thanks!
Best regards
Nicolas
