Viewport / Android / Mobile Friendly HTML Work

I'm looking for a web developer who has an eye for detail.

I have a simple website that needs to work as expected across all mobile devices.

I have managed to get it working sucessfully using meta viewport and media queries across desktop and most mobile devices however when it comes to android it doesn't work as expected.

I've done my research and it appears android is a bit more particular about what viewport and media information it reads so I need someone who has cross mobile experience.

The catch is the code of the website cannot change massively... I'd like the fix to be small and simple.. use of javascript is ok and implimenting additional css resets as long as it's kept to a minimum.

You can see a live example of the page I need to work correctly here:

It's very very basic and its current functionality hides the normal menu and replaces it with a drop menu on most mobile devices... this needs to work on all along with the text size being readible on all and the frame size of the site fitting to the device screen.
