French Polynesia honeymoon help

Wife and I are trying to plan our honeymoon in French Polynesia for July. Looking at Bora Bora but open to other islands as well. Trying to do 7-8 nights on a budget of $15k. Mainly looking to relax and do some sort of whale activity (wife loves whales, saw them in cabo last year).

I emailed an agent at tahiti.com about honeymoon packages and told her our budget and expressed interest in staying at either 4 seasons or St Regis for just a few nights. She emailed back saying this wouldnt be possible for our budget. Im guessing because July is their peak season and also because flights are high as shite right now. I emailed back saying we are open to other resorts/islands or would even go down to 1-2 nights on the above mentioned resorts.

So i guess my question is, which resorts/hotels should i be looking at and whats the best itenerary to get the most bang for our buck? Again, mainly looking to relax, eat, drink, and whale activities. Maybe some light exploring.

Side question: i have the Sapphire Reserve card which provides complementary travel agents. I havent used this feature yet and was curious if anybody has had good experiences with them. Have never had to use an agent before but it would be nice to get as most points as possible if we're going to spend this much and im assuming they can help with that.
