I want to say welcome MS caramel to YT you will love it here.
you can look in the wanted/for sale section and see what is available in your area. good job I see you have done your home work and know what you want.
but be aware no one can guarantee the size only a guess.
maybe a little better guess if they have been into it for a while.
I don't know how small you want one as they are all pretty tiny at first
so you may want to look at older ones like 4mths and up.
hope this helps and
