Some tress, some landscaping, some remolding on home?

There's no way for us to know - first, we don't know where you live.

Second, we don't know what resources are available in your area.

Where have you gone to ask this question? In my area no one will build a garage for you, do any type of in depth/extensive landscaping and/or plant trees or remodel your home - unless you need remodeling because of a specific handicap. The "rules" may very well be different where you live.
