Recommendations for piano (keyboard) teacher

Hi neighbors! My son has been very eager to learn how to play piano (in our case a keyboard because a big wonderful piano does not fit in our house). Anyway, I signed him up for a kid's music academy but the prices are a little bit pricey and I am not sure it is the best place to start. Does anyone offer classes or know somebody who can teach and is available? We are willing to take in home classes or we can go in the place Thanks in advanced.
