Google a home maintenance schedule. The first one I get is from Lowes and seems very reasonable:

Honestly, I would not want to pay for someone to look around for problems because I think you need to learn how you house looks and be able to notice changes. Just walk around for a few minute and try try to notice little details. That way, you can notice if a new hole or crack appears or if some paint starts pealing.
Then, I would find one or more contractors. You will likely need several (such as a handyman service to clean gutters, touch up paint, an HVAC service, and a garden service to trim trees).
