Wanting to cut down a tree but communication line run through it. Is on my property

I have a tree in which I am wanting to cut it down and get rid of tree. However communication lines goes through it, from a telephone pole to another telephone phone which crosses my property, I already trimmed tree back, but I don’t want to mess up the communication lines. I have gotten three estimates from tree contractors, which I cannot afford. Estimate was averaged 1500 to 2200 to have tree removed. I cannot afford this. I was told by contractors that’s why estimate is so high. And it was also stated contractors that if they damaged communication lines I will still be responsible for the cost of it.
