STEEM FOR CROWDFUNDING QUESTION!!

[BuALI]

STEEM for Crowdfunding?

I would like to use steam to create a crowdfunding platform in south america which is very scarce in crowdfunding.

I am looking to implement steam in order to create an incentive to reward project and campaign creators for promoting their projects and campaigns in order to receive the rewards. The model I'm looking to implement works a bit like the following:
Campaigns have a rating system that rates campaigns based on importance and relevance (in case this is a productive project not charity). Coins generated will go to a wallet that will change the coins for cash and give a commission discount depending on the money earned. If the coins earned exceed the maximum possible commission (commission is a percentage of the maximum goal) then we will add the cash earned added to their balance.

We won't be crediting directly with steem coins because we don't want to burden them with having to exchange the coins most people aren't to blockchain savvy and in latin america even less so.

As for charity campaigns there won't be any commissions but we will reward them based on the number and amount of donations received and crediting them accordingly.

Can this be done using Steem?

If not, please let me know if there is a blockchain that works for this..
