Get wheels with more spokes, like the 32-spoke wheels on that Trek. Ideally, have them built by someone who knows how to build decent wheels. You will never notice the difference in weight or drag on your commute or even on much longer rides. Then learn how to take care of them yourself. It is NOT difficult.

BTW, that Trek looks like a nice bike for the price, but you have a triple crank now, while that one is a double.

PS. Is there a reason you have the rear fender up in the air like a shark fin?
