clay sculpture mould maker

I am looking for someone to make me a clay or plaster mould /sculpture of a bee honeycomb with lots of worker bees on it {please see attached photo}
I want it to be around 26" x 12" x 2"
I have not made a bronze cast before so any advice would be very welcome.
I do have more details to add but i will wait to see if you can be of assistance before we carry on.

I look forward to your reply.
