Photography is hot right now but a finicky market. My best advice is to find a niche that makes you unique from every one else out there so you can be competitive.

We recently just started a business and the same old about trying part time first -we lived off one salary for a year just in case it didn't work out. Also have a cushion for expenses cause photography crap is so expensive....within a month out drone crashed and we needed a new MacBook.

Also be great with numbers or get a tax person or accounant. Tax withholdings suck. I do all our books and it's basically a part time job

With that being said, I don't regret it for a minute :-)
