In our experience with several crowdfunding campaigns on Kickstarter, we got contacted by a lot of people. We hired two different agencies and one freelancer. The only one that really delivered, was Boostyourcampaign. From day one the level of service I received from every person I worked with at Boostyourcampaign was exceptional. While one agency charged us a startup fee of $2500, boostyourcampaign got us fully funded, for only a fifth of that amount. They never let us down!
