I am Website Speed Optimization specialist & software developer having real experience about how to Boost speed of any site. My all projects are related to website speed optimization.
For speed optimization I will do all the necessary below things that will make your home page open fast:
5- Remove query strings from static resources(If possible).
6- Reduce HTTP requests.
7- Combining css(where possible within limits).
Please send me site admin login/pass so I can fix speed related issues.
I look forward to hearing from you.
