Headstone for my deceased husband

My husband and love of my life for 27 years, Mike Ralls, passed away November 1, 2014 of a massive heart attack, unexpected.  I had no savings or life insurance on him to pay for the funeral, but a very generous friend raised the money to cover the funeral costs, which ended up being just enough to pay for the very least expensive funeral and burial - 1700.  That has been paid, but because we lived paycheck to paycheck and had no savings, and I'm going to be missing a full paycheck for time I'm having to take off work to mourn, I have absolutely no money to purchase a headstone for my husband.   I want to be buried beside him when it's my time, so I really need a double headstone.  The cemetery owner has said that I can make payments on purchasing the plot next to his, but there is no place that will let me make payments on a headstone.  I have done research on the internet and found that headstones can be as expensive as up to 10,000, but I found one that would work very nicely and the cost is 1500.   I feel like I can't get any closure at all until I've taken care of this last detail and get a headstone for my husband's grave.  I am in incredible grief right now and have racked my brain about how to get that headstone.  This is my last resort.  He was an amazing man and deserves this.  I've never been one to ask for money from anyone, but I am truly heartbroken and in a panic.  If you would like to see his obituary, go here:  http://arkansasfuneralcare.com/2014/11/marion-c-mike-ralls/#comment-262282
