雕像 statue

You may bring the photo to a plaster- cultural, I know there are some in Yau-Ma Ti (新填地街或廣東道). However, I am not sure whether they would do it or not for such a small job. But I advise you to try and find out since you like to have it so much, I guess.
Note: It has nothing to do with Fotomax photo finishing.
祝你成功!

Go to Fotomax to take a look. The make statue (cute type) for customers. No harm to ask there.
