Extract email addresses and details out of set of websites

Dear Freelancer, we are a family business in the music area and we are preparing an email campaign for Switzerland. For this we would need the contact addresses of all Clubs in Switzerland. We do have a list of 900 Clubs and Bars but not with all the information. Now the job is to complete the draft list we have and fill-in missing information. Especially the email address or addresses (in case a club lists several) we are interested in. The source for this research will be primarily [login to view URL] (German language skills is an advantage but not a must). Please mention in your bid also your ideas for further information sources and how you would expand the list as we know that there are more than 2000 clubs in Switzerland. Awaiting your ideas and bids Dieter
