Do you know what the problem is? or what are you trying to solve. ?
The bonding wire (thick copper wire) is normally attached to the pool structure and any lights, stairs or metal components of your pool and then is buried under the decking and returns at your pool equipment. At the equipment pad the wire is then attached to pumps, chlorinators, etc any electrical equipment. This creates a safe grounding path for any stray electricity.
An inspection is required by the towns on pools to specifically check this wire and other things. Was an inspection down by the town's building inspector?
If you know what exactly needs to be done it is a lot easier to hire and direct a vendor or contractor - or at least be able to explain what you want done and how you want it done.
Most electricians should be able to handle pool issues except automation as they kinda have a learning curve.
Or call the building inspector and ask him or her for a recommendation.
