I will offer some feedback, Not sure if your campaign is live, but there is no way I would support it - your perks (especially the 500.00 level) seems broken. You do need to actually make money off of it. Handmade anything is also very dangerous should your campaign actually take off. There is no information, no story, no engagement with your funders, it is literally just the levels and zero information.
Now your concept, which I scoped through your profile and another post, is actually quite interesting. I can see it as a viable business model IF you had supporting documentation, a business plan, have done customer interest surveys etc.
You also need to have a very, very strong community around you. Do you have one? Do you have raving artists who are willing to support you? Do you have any experience with social media, business and the other skill sets you would need?
The major red flag for me is that if you can't get a traditional loan through a bank, credit union, or start-up support through government small business development (or even arts-related grants) Or personal loans from family/friends or supports then there is a problem with your business model, your financial viability, or there is some other major reason the banks aren't willing to take a risk on you. That makes me nervous it suggests you don't have the business background or money management or there is something that might derail your success.
An Indigogo campaign might be a great way to promote and launch your business - especially they type you are looking at - but you are missing way to many key details at this point. It seems like you are shooting an automatic in the dark and seeing what you hit.
EDIT: Okay, I just went through your shortened link and the whole campaign loaded, the longer link I went through the first time has none of your story or updates info, only the campaign side-bar.....On that note:
Your story needs to be re-written so you are not using a passive voice.
People are looking for honesty and deep consideration in the "Risks and Challenges" section. It is how people gauge the likelihood they will get their perks delivered and proof a lot of thought has gone into the business planning.
"If we don’t reach our goal, it’s not the end of the world because we’re still pushing through." - Gah, no! You need someone who has some copy writing or sales experience to go through all of your text. Your using lots of words but your not really "saying" anything.
If you are asking people to help you get the word out and tell their local media and friends and family, you want to control what is being said. Having scripts people can use will make taking action easier and control what is being said about your project.
Now, I do think your idea of a mobile art supply is an awesome idea. My community would have KILLED for something like that (nearest art supply for anything was 4 hour round trip drive) you just need to really dig in and get super clear on the details.
