logo designfor new social network site/business

Need a logo created to begin the forming of a brand for a social networking website for overseas property professionals. the site is like an online magazine but enables property professionals, agents and developers to interact with each other and share information within an online community. The site will have a white background but will have a banner at the top and the bottom. no colour scheme has been decided yet. Would like to see 4 to 5 different ideas which could then be moved to a next level in forming a brand for the site. The logo must have some form of icon part that could be used as a button a little bit like a tweet or facebook button you see on websites. ALso needs to be able to be made like a "Find us on Facebook" button. the logo needs to be sharp, professional and corporate. words that explain what the site is:- connections, community, professional, overseas property industry, grow, share, develop, platform, portal, network
