Can anyone help me with the following ?

Going to produce a range of generic ERA toy cars for retail sale at a price that can be played with rather than static models , similar to the amount of detail the matchbox toys had several years ago before the company was taken over.

See the photo for rough size and packaging.

In addition smaller ones around approx 1:64 as the hot wheels range.

I need designing done and moulds made up to send to potential suppliers

Any help appreciated.
