New Business - What, How, Why?

Well, I have decided to start a small business selling youth sports photos as a way to make enough money (I hope!) to keep buying more camera stuff. Maybe down the road it could be more.
I am starting with the not-so-fun side... IRS tax paperwork and such.
1- When you started your business, did you go LLC, Sole Proprieter, etc?
2- Did you start the official business right away, or did you start making money and then take care of the IRS stuff?
3- What software or system do you use to track the taxes, expenses and such?

Thank you in advance for any help you can provide

I went with LLC. Quickbooks is great.

You can probably just do a DBA (doing business as)

Really all you need is a decent website for ordering prints and the right marketing tools to get people to the website.

Cool - thanks for the response!

I think I am going with Exposure Manager - they seem like a very good company.

LLC, Quickbooks Pro, Don't forget to apply for your sales and use tax with your state asuming there require one. also don't forget you will more than likely have to claim all your equipment as assets and pay property tax on them or at least in the state I live in you do. Enjoy
