Magento Tweaks

I have a client who is getting ready to launch a Magento powered ecommerce site. Everything is installed and running we just have a few html / css design tweaks that I need help changing. I need an experienced Magento coder who can help with 3 small design changes to the default magento theme: 1) I need some descriptive product text fiel to be added under the product title on category pages. This would be placed right under the title but before the "add to cart" button. 2) Small CSS design tweaks like font size, etc 2) We are using a joomla-magento bridge. The bridge messes up the layout on the checkout process. I'm sure this also some small css fixes like width to make the boxes fit horizontally on the page ## Deliverables Please see screenshot in the attached zip file where I would like that extra text field to be added
