My suggestion will be to include "Designer Help" option in the Logomaker because some clients come with logo customization request like - "they want to include a pen or remove the butterfly, or add the stars, eyeglasses etc.." so i think "Designer Help" option will help them to customize the logo in their own way by giving some extra fees as set by the designer.
But one important thing along with this "Designer Help" is that - when the client press the "Designer Help" option a request should be sent to designer if he can accept it or not.. If designer accept it, the order starts.. That's it.. 🙂
