Sorry couldn't read all the posts. To much negativity around Christmas.
Sure it will be tough, good luck!
My advice, first of all if the complex is 40 acres then you have 20 acres or less of grass(from the picture). Do what ever you have to do to get it done in one day. If that means hiring a couple of guys, then do it and use them to expand your business the other days. It will be a good learning experience,
Good or bad.
