Spanish tutor/teacher for 6 year?

Does anyone have any recommendations of a having a Spanish tutor come to my house or for us to go to them for my 6 year-old.  My son only a little knowledge of Spanish (and was previously in a Spanish immersion daycare) but isn’t comfortable speaking.  Effectively, I am looking to slowly get him one hour of tutoring a few times a week just to help him retain and improve his Spanish. 

I see that some schools have one hour of Spanish twice a week as an elective in Elementary school, but I am looking for something more for my son. 

Would appreciate any recommendations!
