Cross-browser, cross-device fixes required

I have a single page , parallax style website which has a number of issues that need resolving before it can be launched. These include

Some Jquery scripting issues
A lavalamp menu issue
Some fading transition effects that are not working correctly in Firefox
Some display issues on smaller screens, including tablets and smartphones

I'd like someone that was available to start within the next few days, if possible. Please register your interest in the first instance and I will send details of the site and specifics for the issues which need resolving for you to provide a fixed price proposal.
