Set up a Project named Power Washer Tasks, or similar. Make sure it is set to be Sequential, not Parallel or Single Action.

Make your first action in the Project be "Rent Power Washer, and change Project", with a start date of March 20, 2009. Add everything you want to do with the power washer either as actions or action groups, and forget about the whole thing. You will see the Project and Next Action in reviews filtered on "Remaining", but only then.

When March 20 rolls around, the Project and Action show as Available. Go get that power washer, and promote your actions and groups to individual Projects as desired. [You included that in the first action so you would remember to do it.]
