website optimization

I am looking for an expert to do full optimization for a website based on joomla 2.5

Can you please remind me your URL so i can have a look?

Alright,
Task #1
The first thing that I see is that you are loading some bad resources:
Line 23 to 38

Task #2
You are loading jquery on line #11, 15, 45,49, from different sources, so it’s downloading and blocking the page

Task #3
Use cloud flare for all your content. Even your images.

Let’s see where that get’s us and we will work on the rest after
