Fitness drawings

I hope you can help me.

I am looking for someone to take these individual fitness drawings (attached) and change them slightly so I do not infringe on any copyright laws.

My idea is for everyone you could make the face just round with no detail and then take any creases of the body. What do you think?

Would this be something you can do?

I would need them done in sets of 20. How much would you charge for the first set of 20?

I need to keep the budget low so hoping we can work something out as I have 100's to do.

Thanks for your time and look forward to hearing from you soon.

Kind Regards,

Kunal
