Convention/Trade Shows

I am thinking about starting an embroidery business and would like to gather more information before I start. I would like to go to some sort of convention/trade show to learn more. Is there a specific convention you guys would recommend? I have seen an advertisement for EmbroideryMart but I've seen ISS more throughout these posts. Also, does anyone know if ISS you have to have a business started already or newcomers are welcome also?

Thanks for any input!

The NNEP Shows are helpful (Embroidery Mart is one) My company, EnMart is exhibiting there in July. They have a lot of seminars and you can see vendors as well. EnMart also exhibits at the ISS Shows. There are seminars there too, and the selection of vendors might be a little bigger than the NNEP shows, although I couldn't swear to that.

I'm thinking the admission fee for the NNEP shows would be a bit cheaper, but I haven't really compared.
