Your target market seems to be the unwise and the gullible: even the purchase of one of these overpriced phones is made using a reasonably anonymous currency (e.g. tumbled Bitcoins) there is a still a record of delivery address.
Thus, these phones of yours are completely unsuitable for any sort of serious anti-Government whistleblowing, and probably inappropriate even for criminal communication, given the ease by which electronic records can be accessed by the various police authorities.
This is either a deliberate scam, or a really stupid business idea.
