I need some help to fix site load speed

I have a website that currently takes very long to load.

Please check out http://stylesafrik.com/index.php?page=categories&parent=women&child1=dresses for example

I need some help to sort this out.

You must have:

1) ability to drill down in code to find the scripting issues
2) ability to recode problems to ensure faster load times

If you have the skills to help, please let us know how much it will cost us to fix.

Thanks
