CSS Repair for Wordpress Theme

I have a wordpress project that I've got 3 CSS issues with. I'm using the latest version of Wordpress and the MarketPress shopping cart framework (excellent documentation). Issue #1 is a CSS problem with the /Shop grid display. The grid is spaced wrong and displaying images in the wrong size. I would also like the code written to display an excerpt of the product description. Issue #2 is that I'd like /store/products/ to also display using a grid without the excerpts. Issue #3 is that I have a widget displaying products that can be used globally on site. I can't get the titles & images into alignment. I'd like this fixed. This should be a fast and easy project for anyone with a background in CSS and wordpress. I actually have some of the code/css pieces, but no time to piece it all together. I need this done within the next 48 hours - please don't bid if that isn't possible for you to commit to. Thanks!
