Nobody in their right mind would even contemplate buying from you seeing as you're not willing to use escrow.
An established business (on this forum) isn't always expected to use escrow but is generally accepting towards it. As a new member, only accepting escrow for an order of 100 pieces + is an outrageous and unrealistic demand.
Perhaps consider accepting a forum escrow for all purchases (at least for the start) until then, buyers beware.
