Logo Design for iPhone App

Hi,

I need a logo for an iPhone app I'm producing.

I am releasing a lite version as well as the full version so I will need the logo, then the logo with the word lite in front of it too, so as to differentiate the versions.

I need a PDF/JPEG format or both, for delivery.

The app Is centred around drinking alcohol with the colour scheme being yellow and black.

More info available on request.

Note:
Payment for this is a maximum of £25.

Cheers.

Dave
