Chris, this place is a forum to discuss treatments and health. Rokybird is an old hand at Curezone, and both knowledgeable and giving in advice. TK moderates a chelation group on Yahoo. Perhaps you should at least consider their input. TK's comments were correct regarding DMPS, and perhaps that should tell you something.
Mercury chelation is particularly problematic for two reasons. One is redistribution, which can make it dangerous; the other is the problem of the BB barrier, which can make it limited in effectiveness. To do this right requires research and caution.
