Piano or keyboard instruction for a Kindergartner

I am looking or actually interested in finding out about piano/keyboard lessons for my soon to be 6 year old boy. I am looking for someone close by or to come to the house and work with my son an hour or two a week.

Any recommendations? cost ideas? this may be cost restictive..but I have to ask

Thanks...any recommendation is good..even group classes would be good

Thanks

Theresa
