Mandarin narration

Does anyone have a recommendation for source for a reasonably-priced Mandarin narration for simple texts (5000 to 10000 words each)? I don’t need highly sophisticated production values, just a reasonably clean recording with no crazy background noise, read at a controlled speed (ie. I would probably need to be in the studio when it’s being done).

My wife has done Mandarin narration in Japan, but I’ll ask if she knows where to get it done in Taiwan.
