Congrats! It's an exciting and sometimes daunting task to plan a DW but the end result is worth it! My friend of mine had a DW in St. Lucia and she loved it but the price per person unfortunately made it difficult for friends and family to attend. In the end the couple decided to change their plans and were married at the Sandals in St. Lucia - just the two of them. They were very happy as it was exactly what they wanted - low key, minimal stress, beautiful location etc. I would definitely recommend working with a TA - speak with a few different agencies, if possible, that way you'll be happy with whomever you select as your TA (instead of just ending up with a random TA).
