Sitter Job in State College, Pennsylvania

I'm looking for someone who would speak and play with our son (he is almost 15 months old) for 1-2 hours, 2-3 times per week during August only. He used to go to the daycare and he entered the age when he absorbs a lot of new words. Me and my husband would like him to have contact with a native speaker when we're still in US. So the purpose of these meeting is language and not babysitting.
