I need 3 graphics for my website

I need 3 icons/graphics to emphasize 3 sentences:

Generate more sales
Retain more customers
Keep your contact list up to date

Its probably more cost effective if you suggest and select 3 graphics from a stock photo site and then slightly amend it so that they fit the colors of our site.

I like for example the icons on http://www.rocketreach.co (see marketing/sales/recruiting icons near the middle) and http://thetheme.io/thesaas/demo/saas-3.html (the customer service and 'act with intelligence' icons)
