Much needed Manual Wheelchair

I want to raise money for a manual chair with power assist wheels. I became a quadriplegic in 2005 due to a diving accident. Since then I have had the same power wheelchair which is getting old and besides I need a manual chair so I can start pushing myself and get my upper body stronger. I do not have full strength in my arms, that is why I need the power assist wheels to make it easier to push myself.This manual chair will also make my life easier, like in the case that I need to travel or if my accessible van breaks down. My power chair is too heavy to get into a regular car, I can only  get into a vehicle with a ramp. With a manual wheelchair I will be able to get around in any type of vehicle. I really need all the support possible in order to aquire this particular wheelchair which I really need.Thank you in advance for your help.Sincerely,Lissette Whitehead.
