This product certainly piqued my interest, but it's probably a little pricey at the moment. And yes, I realise that as a startup producing small runs of custom stamps, you probably can't sell them much cheaper than what you do.
Certainly though, before I'd buy anything like this, I'd want to see the designs in some reasonable detail.
Also, you spelled "purchasing" as "perchasing" on your web-site. As an above-board company you should be very careful about that sort of thing, as bad spelling is a common red flag for sites that are not legitimate.
Good luck!
