I have a yard to bid in need of extreme renovation. Front yard is 55' by 35' and back yard is 85' by 95'. There does not appear to be any grass in this yard anywhere, but there is a boatload of weeds. Yard is probably 70% covered in weeds and reasonably sized weeds too. New owner would like to be fixed ASAP. How would you tear this yard up and start over? 3 man crew, how long do you think it would take?
