Producing vectorised badges

I need a designer that can continue the fantastic work from a previous designer (now gone off to an international branding agency).

The job is to produce a set of pictogram badges that represent a particular achievement (learnt new rhythm, note, technique, etc...). This is for a music-learning website. We currently have in the region of 150 badges already designed.

Work can start immediately. The deadline is set for 4 weeks ahead of this date (08/18/13) when we will be wrapping up shooting of the lessons and begin post-production ready for site launch.

I have attached some examples of the badges to this proposal.
