Grants or Freelance Income for Cancer Families / Caregivers?

I am a cancer caregiver; my wife is a 3 year survivor of breast cancer. As stressing as that is, I know prayer and friends and family really help with that aspect of the disease.

While I am not here to look for work, I was wondering if anyone knew of ideas, places ( like guru ), and grants out there for families (2 adults, 3 young kids) like mine.

I am a programmer for a large hospital. Payroll and medical charging. The typical stuff; ruby, perl, java, sql, etc.

Paying the bills, while tight, is happening on a regular basis. Really what I want is the ability to buy my wife something extraordinary for her 40th birthday (December) and am looking for advice and recounts of experience others have had with various online freelance places like guru.

Thanks!
