My Tae Kwon-Do instructor is looking to make a little extra money on the side. He's hired me to do some graphics work for him, which I'm more than happy to do, but now I'm beginning to wonder if he's done his research.
The area he's looking to get into is very niche-oriented - there isn't a lot of consumer traffic and the startup costs could be huge. I'm afraid he hasn't done his research and is about to sink a lot of money into something that isn't going to pan out.
I want to tell him this, at least ask him if he's done his research, but I can't just come out and say that. I've only known him for six months, and then only through TKD and the graphics work I've done. We are friends, but I just haven't known him that long. I wouldn't know about his proposed business at all if it weren't for the graphics work. That being said, I don't want to see him sink a bunch of money into something that isn't going to deliver.
How can I tell him what he's doing might be a bad idea? I don't want to offend him by suggesting that he doesn't know what he's doing, but I also don't want to see him sink a bunch of money into something that won't deliver.
Note that I am not an expert in starting up small businesses. It's what my family does, so I know the general principles, but it's not like I've done extensive research on it.
