We have developed a large B2B business portal based on Mosets and we are interested in transferring this into K2 and take further. However, prior to this, we would like to make sure on the following:
1. Import 16.800 companies possibility... from Mosets
2. If we can further provide to a listed company a coupon feature ie. they upload their special offer for a validity period of 30 days etc. in different set categories as in structure now.
3. The current site is www.volosonline.com

Thank you,
C. Pashiardis
CEO

This should require custom DB work.

You have to migrate Mosets companies to K2 items through mySQL. As for the coupon functionality I am not aware of a plugin or extension with that sort of functionality.
You have to look for one at the JED or here: getk2.org/extend
