Urgent need for help to remove diseased tree

My name is Amy. I'm not one that's good at asking for help. But right now, I'm in desperate need. I have a large Ash tree that has been destroyed by bore disease and its endangering my home. One limb has already fallen on my roof causing damage. I'm needing to have it taken down as soon as possible, but the estimates I've received have all been around $3000-$3500 to remove it, and I just don't have it. The last few months have been full of unexpected expenses and I'm just at the end of what I can do. Any help would be so greatly appreciated. Thank you!!
