You both have no proof that you can or can't, so why post if you aren't going to be helpful?
You can do so.. You can do a ritual with candles and all that nonsense, but the important part is that you use a mirror in the dark to come into contact.
You must not let the candles burn out or look away from the mirror once the chant(you have wrote) has called the evil one.
A signature will probably be required. I have not wrote a ritual down for good reason.. You must write it yourself or find someone who will share.. Which they probably won't, for good reason.
