Electronics & Appliances coax cable connecter installer help

my internet connection is poor to useless and i found the modem end of the antenna cable fried, i believe to a close lightening strike. i got a band aid on it but i'm lucky to get 2G for a few minutes at a time. does anyone know of an installer/shop/someone who can come to the upper bacong area and put an new SMA-Male connecter on my LMR/coax antenna to modem cable? i need the connector at the modem end of the cable. cell numbers would be great. thanks.
