Are there any reputable wholesalers for crafting supplies?

I am looking for a reputable wholesaler(s) for crafting supplies. Specifically, beads, florals, glass vases, decorative gem cuffs, candle making supplies, etc. Purchasing individual items at a Michael's or A.C. Moore craft store becomes too expensive. I am exploring the idea
of a craft/party supply business & I am in the research phase, so any information would be helpful. Eco-friendly produts would be most welcomed:-)

Also, I am interested in creating my own invitations. Can anyone suggest great software? I purchased the "Greeting Card Factory - Version 7 Deluxe Edition" yesterday & I am not too fond of the designs. I need a more mature/classy type of a program.
