senior professionals BUSINESS & TECHNICAL english group

Hello, my name is Vicente.
I would like to create a language exchange group (Eng-Spa) for >30 years-old professionals who are interested in subjects beyond Justin Bieber or Game of Thrones.
My point is creating a group of people in Madrid who want to practice and improve their language skills for business and technical porpoises. Firstly I´ll create a web site for the group to arrange activities as soon as some people join it.
I’m Spanish and a Construction Engineer. My English level is B2. I know some other Spanish professionals interested to participate.
Then:
-	If your mother tongue is not Spanish…
-	If you are interested to practice English or both English and Spanish language skills…
-	If you are a senior professional of any field…
-	If you live in Madrid or its surroundings…
Contact me! Join this project!
I would appreciate also your suggestions.
Thanks.
