Looking at your iwconfig, it looks like here is no such device as "wifi0". That was the error given by wlanconfig. Try using wmaster0 instead of wifi0.

Also, since wlan0 is already in use, you need to specify wlan1 instead of wlan0

Code:

sudo wlanconfig wlan1 create wlandev wmaster0 wlanmode ap

good luck,
