Hi Rachel,

I have recently got a quote from this guy, who is very quick to respond and has good reviews on his store

https://www.etsy.com/ie/shop/TheSupp...f=pr_shop_more

for a custom stamp its around 130 dollars but he does have a lot of beautiful (well-priced) stamps in his store that might suit your design idea and you can maybe work around the need to get a custom stamp made initially.
