Customize WordPress Theme

I need a wordpress theme to be customized for my site. I am currently switching my site over from joomla to wordpress. ? The site is small, only about 5 pages total. I have already installed wordpress and a theme, but I need the theme to be customized to my needs. ? I have already created a logo. ? Here is a sample of the kinds of edits to the theme that I need: I need to get the urls working. ? Right now I have Joomla and wordpress installed and the urls for wordpress are not working. ? I need to get them working before I switch the site over. 2. I want to get permalinks in place. ? I want the urls to be simple - this may involve some mod_rewrite unless you know an easier way to do it. 3. I want the post titles to be listed in the sidebar with a title of "Products" 4. I need a few headings/links removed and/or replaced with other text 5. I need about 4 pictures to be displayed in the sidebar I don't need any major layout changes.
