Hey guys! I've been asked to do a cake - Ninja Turtles, along with 20 cupcakes. Since i'm just beginning, I'm wondering if any of you could give me advice, tips, maybe an estimate of what you would charge for this? I know I need to make a profit; count in supplies, delivery, etc. Anything would be helpful. TIA!

Photos courtesy of pinterest, this is not my work.

What is it you need help with? You are a little too vague here.

.........give me advice, tips, maybe an estimate of what you would charge for this?..........

I would NOT make that order!  It is a copyright infringement.  You could be sued by the owner of the *original* creation.  Just because someone else made one does NOT give you the right to do wrong.

If you search not only this site, but all of the internet you will find many, many discussions in regards to this issue.

Just a couple of search results for you to consider.  There are many more.

You could make a generic cake like brick pattern on the side and a man hole cover and then whoever has ordered the cake would need to buy figurines from someone who does have copyright agreement to sell them. 

You would have to contact the copyright holder and ask permission to use their image or likeness in your cakes. I have made licensed characters for my own children but never to sell. 

Oh you MIGHT not get caught but.......is it worth the chance that you could be fined 1,000s of $$?

Again, as I said, just because one person (or in this case, many) have chosen to break the law and chance huge fines do you really want to do that?
