Help a Blood donation organization

We have a voluntary blood donation club. By which the upper-middle-class people also get free blood from the lower classes of society. We find out the blood donor through Facebook. Then take him to the patient and then collect the blood. Our organization has funded the students. Currently our "Bogra Online Rokto Dan Songoton" is a familiar and trustworthy organization in Bogra town. In the special days of the year, we calculate the free blood group. Now we need a blood-storing machine of this organization. Because we get some blood donor who does not need blood immediately. Sometimes I can not find the blood donor. If we can save the next need of blood beforehand, then this problem will be solved. The cost of the machine is very high and it is not possible for us to carry this expense. Because we are all students. Please help us. This will save lives of many people.
