Help me save some kittens?

I don't ask for help. It's not something I do. But I'm on a time crunch and I'm going to lose access to the Ginger kittens I've been socialising for MONTHS, so I can get them desexed, vaccinate and Homed. I could use your help. Every little bit counts.

Behind my office is a whole colony of feral cats, most 4-8 mths old. I have been slowly working with 4 of them to get them to trust me enough to catch and get medical care, but I was working on a free timeline. I have since learned that we are moving offices soon and I will no longer be able to access the kittens. So, now I'm on a deadline. I have already reached out to every single rescue that services the area - and many that don't - and none are able to help me. They themselves are overrun with kittens, and unless these ones are pregnant, cuddly or injured, they can't help. So I'm taking it upon myself to do what I can with the kittens that will come near enough to me for capture and treatment.

Please help me help them. As these boys get older, they are getting into more territorial fights with older un-neutered cats, and they won't survive. Please help me to help them. To get them medical care, to bring them into my home and help them feel safe enough to love humans, so I can find them homes.

Every little bit counts, and I thank you in advance for your generosity and compassion.
