Hi, Minyassa

You have an interesting question there. I do make it a point to help people in need who are less fortunate than most without first thinking how or how much they are to pay me. God provides that
The real masters may it be feng shui, reiki, pranic, qigong, acupressure, acupuncture, etc. will not put a price for their services. They will willingly help out folks especially those in need provided those - meaning the patients - really make it a point to be open to the assistance they are to be given. Those who are fortunate in life who have been helped upon should contribute but that is really up to them.
Its not bad to ask for a different mode of payment as that is also a form of energy returned to you. If the person cannot offer anything save thanks I make it a point to accept it on the condition that he helps out folks in whatever ways he could when he could.
I sure wish I and my wife can help you out but as we live in the Philippines it would be cost prohibitive for us to journey there :(
My bit of advice for your organization is to locate a good place to call your HQ. Then find out if there's a septic tank - well, that's common here but I'm not sure if its used in the US - at the place as that is one major negative chi generator. Next, you are to place a cactus plant - any of the cactus variety will do - over the septic tank AND inside the comfort room/water closet/toilet ONLY. Believe me, that's a very effective solution for financial problems using the old school method. He he, its quite cheap too just make it a point to always double the number of cactus you are to get so that one can receive sunlight while the other is doing the cleansing job.
