There is always a danger of turning a hobby into a business, that one thing that you loved to do so much soon loses it's shine when it becomes a "have to" not "want to"...
That being said, like many starting out, you need to know your market or "if" there is a market...and if that market will provide the income you need to pay the bills and keep the family fed.
From my observations it seems that now "everyone" thinks they are "pro grade" photographers, so this is something to keep in mind, as many on this forum have stated in the past one of the biggest hurdles in the photography business is "Uncle Bob"...
It seems that anyone that can afford a half decent camera is now opening a business, I think this is where it becomes difficult to get your foot in the door (the salesman in you has to step in at this point), good portfolio, good website.
i.e...just recently a friend of mine got married (low cost) she posted a link on FB of the wedding photographers website, I have to say I was shocked at the poor quality of the photo's this person had used to promote their business...even though they were cheap $1000 for the Premium Package, I would expect better quality (photo's & PP)
You mentioned that you would eventually like to "sub-contract" work to others, maybe this is a place you could start...Find a similar business and see if they will take you on as a "subbie"...
This way you get experience, you get the companies contacts and knowledge, you can probably pick and choose your jobs or hours... If you find that it's what you want to do, in the future you can go out on your own (maybe don't sign too many contracts that may prevent you from moving out on your own).
Photography is a rapidly changing business, those 8x10 that once were framed and hung proudly are now Instagram on FB.
