I'm going to be blunt here but your request wouldn't inspire me if I were a potential business partner.
There is no mention or description of your plan. Where is this property situated? Why have you choses Sweden? What kind of
personal would you be hiring? What will this retreat offer potential clients? What's your business plan/date/financial requirements? How will this retreat be structured and set up? Dates? Who are your competitors in the given region etc, etc;
I think that you should be the person who will be giving answers and not the other way around.
