Digital illustrator - this weekend

We are looking for an illustrator who works in 'illustrator' to 'tailor' some book illustrations which are predominantly clip art. We need to soften them and add a bit more charm to the overall effect. pics are in two colours. All simple. Main illustrations are done, but we now need to polish (by overdrawing). Some are drawn already in indesign, remainger in illustrator. The illustrator has to have a touch of humour in his/her style. All in all about 30 images, but some already done/will do.
Files can be supplied within indesign doc (with links as illustrator files)
We think about 1 day's work. But it needs to be done across this weekend.

Note this is not starting from scratch. It is evolving work in progress.

Illustrator must be UK based, and ideally South England
