548089 Joomla Site Design Update and Content Addition

Dear All, I have a joomla site, the project is almost complete but it need some tweaking (mainly Drop Down menu) I am not familiar with Joomla so i need Clarification of some issues and i need some one to add the contents i have but you need to make the text uniqe as some of the content is generic and i want to make my site unique. So I need: 1. Fix Drop Down menu issue. 2. How to Add/delete images to our Clients Section and change links. 3. How to Add/delete Images on TOP of site and Change links. 4. There is a section on the right when you click on any service that say our services include: and links ( i think this is generated from joomla but just to be clear what i need, if it is reading from the services database then forget it). 5. Add Content as discussed above (around 10-15 pages), Please make sure you make the text unique, meaning saying what i have in other words :). 6. One last thing is there a way to make the http address like mysite/myservices/service instead of the long joomla address (URL REWRITING). That's it , project need to be completed in 4-5 Days maximum. [login to view URL] is the link to my site
