I am going to go with the red option. I am really hung up on maintaining a symetrical look so the pink option does not really work for me.

Ezlyman,
I think the quote came in higher because of the Timbertech boards that I want to use. The quote for regular wood was about $4,500 which is about in line with what you figured.

One more question though...I have told the builder that I want the pier to be as low to the waterline as possible. I know the maximum height of the water because I have installed an overflow pipe. What is everybody's thoughts on the height of the pier?. Are there any downsides to having a low profile pier?

Thanks for all the feedback. I am ready to get this build so I can start posting some pics of the finished product.
