Web page and business/legalities

[AKmik]

Hello all,

I was wondering if someone here could share a little experience and knowlage with me on this one.

I am thinking about setting up a web page to sell a small volume of knives and my main hobby, gunstocks. I was wondering where is a good place top get info on keeping it legal without over complicating my life.

Is a business liscense required for a small volume guy,.....where does a hobby become a business. Is there a minimum ammount of sales required to make a liscense a necessity?

Any info is appreciated.

Mike
