Create 50 LinkedIn accounts with over 500 real connections each

I require 50 LinkedIn accounts with social media marketing profiles (in batches of 5 / 10 every week), with real connections of 500+ for each account and few group memberships. The profiles should not be banned by LinkedIn for any spam connection requests and have to be functional for a long term. The accounts are going to be used for posting promotional posts and messages for clients and creating interactions within each other to promote a product / service. Immediate requirement, can work long term.
