Hi there, so I would say roughly it is going to cost about $1200/pp depending on where you stay and perhaps the time of year. I am getting married at the Somerset on Grace Bay and it costs each of my guests roughly $1200 to attend (air and hotel for 4 days/3nights). At the Somerset there is an Intimate Vows package which is $2800 which includes wedding services of a coordinator, officiant, processing of legal documentation and mailing of marraige license, choice of ceremony and reception location, pre-ceremony set-up, bottle of champagne, in suite couples massage, bridal bouquet and groom boutonniere and wedding cake.
There are however other planners on the island that can probably offer something along the lines of what you are looking for. Look into Diane at Island Harmony.
Also Krys Mann from TI is on the site and is an invaluable source of info for anyone even considering T&C. Here is a link to one of her threads where she discusses the difference between several resorts.

I think if you search through all the T&C threads you'll be able to find exactly what you are looking for. Good luck and don't hesitate to ask any questions.
