Joomla PHP developer

Hi Folks

I am trying to improve performance on our Website, and one of the big problems we have is that there are 15 Javascripts on our pages.

So i would like to try and reduce the number and combine the remaining ones into one JS file throughout the entire website, so our http requests are reduced.

We are currently using JCH_Optimize Joomla Plugin

http://extensions.joomla.org/extensions/core-enhancements/performance/site-performance/12088

but this does not combine them.

Ideally i would like these social buttons to be Asynchronous

http://extensions.joomla.org/component/mtree/social-web/social-share/social-multi-share/20357

Website is http://businesspages.ie/

and examples of where these are shown in listings is

http://businesspages.ie/bicycle-shops

I also want to include the facebook send button here

So buttons needed are

1. Facebook Like
2. Facebook Send
3. Linkedin Share
4. Tweet button
5. Share button

Thanks

Scott
