Much respect to you for initiating this venture. I hope you can recieve as much ideas and feedback as you need to make it work.
A quick tip of my own: You can have 2 Paypal accounts of your own.. so long as one is personal and the other is premium or higher (the point is, both can be free). This may be useful for your further testing purposes.
Keep up the excellent work. Keep above the scammers at all times. Hope to buy some BTC from you when its out of Beta.
