Eating Halal in the US

As I prepare to say Shahada, I have been faced with the dilemma of what will be lawful for me to eat once I revert. I have searched my area for halal butchers, but have had no luck in finding a place as of yet. I have read many differing points of view on whether it is lawful for Muslims to eat meat slaughtered here in the US and widely available from the large grocery chains. I would just like to know any tips the American Muslims here can share on how to eat halal in this country. Thank you all very much for your time and help!
