There are a lot of businesses where people help you relocate, yet I don't have someone in perticular I can recommend. Have you done research on Costa Rica to see which areas could be the best fit.

You may want to look into the online version (which would be cheaper) of the conference. It is a good way to get lots of info and start to figure out if Costa Rica is right for you. Are you looking for a rental or to purchase a property? I know some real estate agents I could recommend depending on the area you are interested in.
Feel free to give me some more details into what you are looking for by sending an email and I can try helping you more. 🙂
