Summer help needed for 6 yr old boy - Full-time / Part-time

Hello we are a family of 4. My husband and 20 yr old son both work from home and occasionally out on the road. We need help keeping my 5 yr old son busy with learning activities and outdoor fun. No house chores required other than heating up his lunch and snacks. I have a 5 yr old son (turns 6 in August) and in need of a sitter August 11 - 29th. Monday-Thursday (some Fridays) 9-3pm. He then starts school in September, we may need assistance for the occasional date night.
