There several different groups other than the House of Netjer (AKA Kemetic Orthodox). A simple internet search will locate them easily enough. They always want more members.

Here a few that I know of, but I am not a member of any:

www.thelivingnuhati.org/

Personally, I prefer solitary practice because all of the groups I have found have this intense hierarchy, and all I am interested in is honoring Netjer, not worhsiping the ka of the head of the group and worrying about titles.

You've probably found something by now, but if you still lurk, I hope this helps!

another group you might be interested in, is a temple and school in New Hampshire, called Akhet Hwt-Hrw: www.hwt-hrw.com
Although they are dedicated to Hwt-Hrw (Hat-Hor), they do offer instruction in religious rite and the like.
