Help finding a business phone service

My father & I are electricians. We have 3 long existing numbers. One for business that is 40 pkus years old. The second 30 plus and a fax number.

We work out of the house for the business. We had Verizon land service. I am looking at jumping elsewhere.

Any recommendations? Such as comcast for business or such? We are a small company and such need lots of local and a good amount of long distance. I also have faxes which need to be sent far away to specialty suppliers.

I need to port my numbers. We are not too tech savy.

Thanks in advance.
