Need someone to install a gate in my fence

We are new home owners, the city tore out our old fence which backs up on 111street (across the YMCA), we are not too happy with this but got stuck with this new fence which now no longer has a gate. My girlfriend takes the bus from century park and needs to have a gate leading out the backyard to get to the station. I need someone to remove part of the fence and swap for a gate.Thank you!!
