Page Speed optimizing website browsing

Hello,

Most pages in my website rank below 50% when running page speed (http://code.google.com/speed/page-speed/) to understand bottle-necks in browsing and areas of potential improvements in different pages (taking into account the use of WordPress to manage the site).

I am looking to significantly improve the speed my website is loading and looking for suggestions.

Please also review: https://developers.google.com/pagespeed/#url=http_3A_2F_2Filanwittenberg.com_2F&mobile=false

Please describe:
- your skill level with reference to previous jobs
- your suggested action plan
- the expected quantifiable result
- the fixed cost for the project
- the expected timeline

Thanks,
