Design a moneybox in 3D

Hello Freelancers, I need to have a 3D design made out of a simple JPG. This are some kids that are supposed to be a moneybox with a small plug/hole below so that the person that uses the moneybox can open it with no need to damage it. This design is for a plastic-made moneybox, we don't need the shapes to be perfect or edgy We need them to be curve and that the curves aint that perfect, We will paint over the moneybox with the colours and that's why the curves dont need to be so perfect. The moneybox-kids are supposed to be 20CM tall, you should make it completely proportional so that it goes with the human proportions. I have the idea that it has to be 20cm tall and about 8 cm in depth, maybe 10 width... Up to you. This is a moneybox design, it should not have any separate pieces or anything, this are 3 kids and 3 different moneyboxes. Any questions please ask. Check attached image (yeah its 2.5MB, its huge) I can pay $300 USD TOP, I will consider the best price/reputation.
