Need New Wheelchair

Hi my name is Mark. I have a condition called spina bifida which one of its side effects is me having partial us in my legs. My family cant afford to buy a new wheelchair. I want to get the "Top End Crossfire" all terrain manual wheelchair, and its list price is about $3250 but after all the customizing it is about $3600. I do a lot of riding on all types of roads and trails and thats why I want this wheelchair. Thanks for your support!
