I need my wordpress travel blog website optimised for speed and performance

General information for the website: It takes 18 seconds to load - i need to optimise this.
Kind of development: Customization of existing website
Description of requirements/features: I need someone who understands website optimisation and performance.

You can see from the attachments that the site needs some serious optimisation - these charts etc should be familiar to you.

This will likely involve removing size inactive plugins, resizing images etc. It should be a fairly easy job.

please only offer reasonable offers - i'm not looking to spend a lot here.
