Love a carbon copy cause it gives all parties the same info if questions arise over prices or service.
My only suggestion is you offer a lot of services. For instance your weed program is listed separately. Maybe give a season package and show what they would get?
Also we don't do a lot of spring clean ups but that seems to be a seasonal service. You may only sell it from march-may. Then it's still on your estimate form.
Keep it simple is what I find here. People dont want to be overwelmed. You may list seasonal services in a separate box.
