Feral Cats Needing Relocation

I have been rescuing cats and caring for a feral colony for the past six years.  A nice couple has allowed me to feed six feral cats and have shelters on their property all this time.  This is the place the cats know as their home but one day there was a For Sale sign up and it became clear that I needed to get the cats off the property right away to safety.  Both this home and the home next to it will be demolished - so I bought traps and equipment (cages, transfer traps, food and water bowls) to bring them to my home.  After about a month I have found a sanctuary whose fee is 5,000 dollars for six cats with the understanding I will send food for them each month for the rest of their lives. 
It was also necessary for each cat to go to the vet for FVRCP and rabies shots as well as the FIV/FeLV tests (aids/leukemia).  And lastly, five of the six cats required a dental to remove their rotted teeth.  So the vet bills were exorbitant totaling over 5,000 dollars for the six and the equipment costing over 1,000 dollars for a total outlay in excess of 11,000 dollars.  Since I could not be prepared for this financially I am asking for help with the sanctuary fee and beginning food costs if anyone can please help - the cats and I would be very grateful to you.  Without this help it would be extremely difficult for me to secure their safety - I thank you for your kindness. You can view some photos showing some of them prior to rescue, and while in my home waiting for a sanctuary,. There is a photo of Wesley and Logan (two black cats) waiting at the vet and Clarisse and Daniel in their cages. 
Theo, Daniel, Clarisse, Reese, Wesley, Logan and I thank you from the bottom of our hearts.  No amount is too small to show support.  Thank you for reading my post!
