Business ideas? Graphic Design or Photography?

Hey Y'all.

I just moved across the country and will soon be attending college here. My father in law is pretty filthy rich, and would love to back me in some sort of business venture, but I haven't any idea what I would do.

Basically, I've been doing graphic design for six years. I'm very familiar with photoshop and illustrator/etc, but not so much with a good 'ol pencil and piece of paper. I'm familiar(ish) with a camera, and have everything I need to edit RAWs and post-process pretty well. I have experience working in advertising for a newspaper, as well as making all sorts of fliers and concert posters for churches and businesses and the likes. Basically my best skillset is image manipulation and a good fundamental sense of design.. plus maybe tech work and printing. So what on earth do I do? I could do a run-of-the-mill photography thing, but I'm not sure that's the best use of me. I guess I'm just looking to brainstorm.

Thank you, looking forward to some advice.
