I am not sure where I could find you a doll modeled after Miku specifically, but I do know of several companies that specialize in creating anime-style sex dolls, which you could use as a base to create a Miku doll with the right cosplay materials. The companies you would want to use for the base doll would be either:

>Aotume (TPE. Can try to match any anime character, and does a lot of smaller dolls)
>Elsa Babe (Silicone. Has a few different animation styles in their face options, also has several options for vaginal texture)
>Irokebijin (TPE and Silicone options. Not as many customization options, but they're good quality for the price).
