This is what a business in Finland was looking for in their illustration design

We are making a storyboard to our http://vainu.io landing page that tells the story how and why to become our customer.

Illustrations are following:
1) Illustration of iMac showing chart. ("Try with your own numbers")
2) Illustration of customer service calling you back ("Drop your phone number and we'll call you back in 24hrs")
3) Illustration of connecting to Facebook, Linkedin, Twitter, Salesforce, Zendesk. ("Connect to your Social media and Business apps")
4) This Illustration is iMac+iPad+iPhone with empty screens. We will add screenshots as gif animations on top of this. ("Select the best of great candidates to make a sales call.")
5) Illustration of your customer making a sales call on iPhone. ("Start selling more with amazingly fun and productive context aware iPhone app")
