wordpress development help

We have a wordpress site that was developed form a the Coda Blue theme that has some bugs that need to be worked out. The theme has been changed. I have completely changed the structure of the loop and am having some problems with that that need to addressed. There are some issues with the menu that need to be addressed as well. This project should be pretty simple for anyone with development experience and experience with wordpress. The site also needs to be compatible with all browsers. I developed it with respect to google chrome and am having problems across all browsers. Main 3 items that need addressed are the following: browser compatibility, menu fadethis function, loop functioning. In regards to the loop. The "next page" button simple returns the page you're on and doesn't go to the next 10 blog posts. Thanks for your interest in this job and we will answer any questions you may have. Thanks.
