If it is for work, then it is NOT for fun, it is for work. If you have clients, potential clients, and their families showing up on your doorstep, and your goal is to give them a FUN experience, then don't look to cut corners and make it a weak experience.
This is all on you, and it WILL all be on you if you don't deliver the promise of a enjoyable outdoor cinema if that's what your promise was.
There are many good recommendations above, but I would not get a projector designed for a 120"-150" screen in a dark theater-like room (Epson 5030) under any circumstance based upon the size of the screen you are talking about and the environment you are putting it in.
Lumens over resolution will matter. Epson is the way to go, but I would go for brightness over contrast hands down. I would also STOP calling it 'fun'. It's not for fun for you, it's fun for others, and if it is at work, then it's a business function, it's a tax writeoff, and if you deliver a bad experience to the customers with your name on it, they will remember. If you deliver a great experience, they will remember that as well and it could drum up a lot more business, especially if you do it a few times over a Summer.
Definitely look in the used market though as some options were presented. The Epson clearance store is also a good place to look to save some money.
Nothing wrong with saving some money, but I stopped going to a local outdoor 'free' setup when they had technical difficulties they couldn't figure out. It made a cruddy evening for our family and we just went home and watched on our own setup. It is business and will reflect according to the experience that those who show up have. Like everything else, it may have some risks that outweigh rewards, or it may have major rewards that pay off in future business worth a great deal of money.
