I agree about enlisting the help of a quilt guild (or two) - they will be your customers! Most quilters are sooooooo suppportive of a LQS and would love to help, even for free, but maybe you could add an incentive: say for a $20 gift card or something? Also, that would help you get connections for good part-time help when your success comes (hopefully very quickly.) The hard is part is leading up to the opening. I can feel your overwhelming fear. But do what you love and you will be successful. That's what my mamma taught me anyway
