Headstone

My mother passed on April 18th, 2011. We have no money for a headstone - as I type I have $35 in my account. I just started a new job after being unemployed for over a year and Im struggling to raise my two kids, my dad is underwater on his mortgage and my sister is raising two boys on her own with no help from a deadbeat dad.

I went to visit my mom today and can only tell where she is buried by memory and the slightly sunken ground. It was very sad to go there and see her unmarked grave.

Can someone help me figure out how to raise money for a headstone? My mom deserves more than this. If verification is needed I will do what I can to provide whatever is required.
