I think you are thinking along the right lines. Do a bit at a time. But first plan out what you want where. Where will the flowers be, the veg, the lawn, the wild bit, the rubbish bit for compost etc? Plan large and work as much as you can manage at a time. Will you be putting in paths? They should be on your big plan and put in earlyish for pushing your wheelbarrow up and down. Starting nearest the house would be easiest then working out. Will you have a patio? An eating area? A pergola, a trellis? Long grass can have paths mown in it to make it look as though it's intentional wild garden. An acre is a lot. You could have an orchard!
Have fun, but it's hard work. I know, I've done it
