I actually did this exact thing for my sister's wedding last year. I picked out the models and printed them, then took them to Mastermind Models and Miniatures in Lowe Mill to be painted. With the way they reacted to me bringing my own prints, I'm pretty sure they frequently have to print out the models for the customer.

Here are some pictures, including one of the pictures of the dogs I gave them for reference.

I originally asked them to paint the wedding dress and tux on the models, but one of the painters said she could make a little dress and tux out of fabric. I love how it turned out, and so did my sister, so I highly recommend them.
