Hi there,
Serial crowdfunder here. Have backed over 3000 projects, marketed many and worked with my and other crowdfunding agencies in last 5 years. For instance, you may Google: Shabaz Kickstarter
Before you accept the bid, please let me have a few details regarding your business, for a general feedback; checking the feasibility of campaign. From what I understand, there are slim chances for people to fund collectible items of a business if not well known. However, happy to assist you as a consultant and guide you proper, if the business is well established and you want people to get excited to support for rewards.
Setting a two day deadline, but will discuss more on that as per your requirements. Hope to hear more soon.
Thanks and best,
Shabaz
PS. just back to freelancer portals only today, after many years :)
