3D models required of characters created for book concept

Hi there, my names Andrew , I took the opportunity to give up the day job and concentrate on a project I’ve been working on for a number of years. This isn’t a vanity project it has to work and make money or its back to the ‘grind ....It’s a “children’s book”! ‘Don’t Groan”I know every man, dog and celebrity is at [login to view URL] if you look on other bookshelves there’s a lot of rubbish. I’ve created a number of characters and several story’s based on adventures I’ve had with the grandchildren, with a slight twist. I Currently process of illustrating the first two books which is taking longer than expected. When I come to sell the project which is my ultimate goal ,I want to be able to show the potential of the characters in different mediums and think 3D models is the way to go. I need to past this work onto someone who can take my sketches and create the models I just don’t have enough time or skill set to do the modelling . I am quite happy And open for creative input advice and collaboration. I want to be able to use the models ie post them out in a file format (industry standard0 so when I am discussing the project with potential clients they can imeadiately see what the projects about , I will take your advice on this. I have 6 main. Characters and a supporting cast of villains . Have a look at the characters below let me know if your interested in the project , I will be able to provide sketches when ever required I would like to be able to take the rendered models and get them 3D printed eventually so I don’t know if the designer needs to take this into account when creating the models 3d models
