Design circular cards

Hi

I am looking for an illustrator to help in creating some circular cards which will contain a set of letters. Each letter should be contained in a shape (most probably a circle). The position of these letters could form an abstract shape similar to these:

etc

We need to come up with a set of shapes similar to the above shapes in each card; ideally 10-15 shapes. The card diameter is 105mm. At first we need to design the cards with random letters and with random color. Later on, I'll provide what letters should be added in each circle.

Please let me know if you have any question.

Many thanks in advance for your bidding.
