I need an illustrator for a children's book

I need an illustrator with a unique and creative style, perhaps similar to Oliver Jeffers or Quentin Blake, to illustrate a number of new children's books (but starting with just one, as a trial). I'm looking for something fairly quick and simple, in a sketch/watercolour style.

The book features about 15 pages and each page would require one large illustration. Perhaps one small sketch in addition on some pages.

Repeat work is likely. You will receive full illustration credit (on the cover).

The story text will be provided in full. Most of the illustrations will feature a small boy, a nest and some birds. It's intended to be humorous, so the drawings need to fit with that style and be bold and impactful.

Kindly send examples of appropriate work you have done in the past.
