Just wanted to say good luck with finding good homes. If it helps we just had the same situation (not being abandoned by the Mother but unfortunately so called human beings). We did manage to find wonderful homes for all of them - did the usual which I am sure you have done - adverts in the supermarkets, vets, Mairies office and just about any where we could think of (with pictures seems hard to resist). We wasn't inundated with calls but certainly enough to find them the homes. I think your offer to pay for neutering should certainly help.
