Recommend any plumbers for a basement bathroom installation?

Hi,
I’m in Gowanus/Park slope looking for recommendations for plumbers that are experienced with installing basement bathrooms. I’ve got a basement with a W/D and slop sink hooked up to a sewer ejector pump that works great, but would like to remove slop sink and install a small pedestal sink, toilet and shower stall. Anyone else done that or have a any experiences or contacts to share? We just had a kid and are in dire need for those facilities. Thanks in advance
