In photography, you don't start business, business starts you!
Okay, that's pretty meaningless bit like others have said you can't expect to just hang your shingle and things get going. If you can set some realistic goals with the financials outlined, maybe your tight wad husband will loosen the purse strings?
I'm taking a couple of aftenoons a week to network and meet new people. I have printed a small pack of samples and am using that with a business card as a leave behind. My website is getting up to date and the administrative side of the business is pretty sound. There are probably a whole pile of thing you have yet to do outside of actually taking pics, while you build your portfolio make sure all the other pieces are in place. How's your invoicing system? Do you have your contracts in order? How do you back up your images? ... And so on.
You might have to check your pride and just basically beg for work. If you discount your stuff make sure the full price is shown on the invoice, doing so will set a real and sustainable value for your work.
