In Process

I am in the process of starting my business. I have all the information that is needed the business name, outline, all the products, everything. The only problem I have is that I don`t have a portfolio. I have done events at weddings. I was wondering if I could still start the business without a portfolio, but then after the first wedding or event could use the photos from that? Would I get business without a portfolio, what is the plus and minus of that? Will I manage still on getting clients. I am a very hard worker and stressed out trying to get this business started. Could I use photos from magazines and not get in trouble for it? Please help!!!
