I would strongly advise you to keep looking for a real teacher as Reiki attunements should be carried out directly on a one to one basis in my opinion. It is not the same as sending absent healing.
It is important that you find someone whose energy feels comfortable, that they are experienced and you feel you can trust them. Reiki symbols can be messed up with unfortunate consequences for the recipient. Your Reiki master should be someone you can turn to if you need them. Ideally they will run their own Reiki shares. Don't rush things. Be patient and if you are really meant to be attuned to Reiki either the teacher or the sum of money will materialise.
Do be aware that there are other healing energies available to us and Reiki is just the best known- that doesn't mean it is necessarily the best for you. I use many other energies that I have been shown how to access over the years and Reiki is only one of these.
