Where can I (locally instead of online) an objective lens?

My son has a science experiment due THIS WEEK and I need to buy these items:
objective lens: 38 mm diameter X 300 mm focal length
eyepiece lens (size of a 10X tripod magnifier)

Can't order online because I need to buy it today. Any suggestions?!
