character definition - open to bidding

Dear Sketchius, I like your draws. I need now another thing , before starting the book illustrations. If I send you a sketch of a character, can you add features and make it more striking and nicer, put the sketch in photoshop and add colour, as create a family? Before I need to ask you to sign the NDA, then this ILLUSTRaTION BY THIS EVENING , and then I give you the book illustration to do. Please give me also the price for 16 book illustrations for the book. Let me know if you can do it ASAP Anna
