Where can I get gold extracted from electronic devices?

I have a few broken cell phones that I would like to extract gold from. I have searched all throughout my town for refineries that can extract the gold for me, but I have had no luck finding any. I would extract the gold myself, but there are too many complications to this, including the fact that I have no access to any of the chemicals used in the process and cause I have no experience with chemicals and don't wanna put myself or anyone else living with me in danger. Is there any way that I can send the phones to someone who can extract the gold for me? And if I can, can anyone give me that company/persons contact information?
