will make custom sets for you, if you message them (email, pm, whatever). They will price out the set including the pieces you ask for.
There are many on Etsy too. One of the vendors
I really like that has made custom sets is JillMarie from Bosombuddiescreations. I think her Etsy store is under that name, it's been a while. Another I know from Etsy that makes custom is Suburban Sugar (Crystal).
There are many great vendors
out there, and most are accommodating if you work out a special order, I've found.
