Looking for a Triathlon swimming coach - any tips

One of my proudest achievements last year was to complete a Triathlon. I did it shortly after passing the half century mark and it definitely helped me feel like I will have many productive years alive ahead of me. Therefore, I decided that I will complete one or two Triathlons again this year.

I am not necessarily aiming to be fast, but I do want to make sure I am able to comple the course. I am reasonably confident that I will be capable of finishing the cycling and running legs. Unfortunately, I am not as confident of the swimming leg - typically I need to stop a few times to catch my breath and check direction. I think it would be a good idea for me to team up with a formal swimming coach for a few sessions. Does anyone have any advice for me on who would be a good person to go to for advice?
