This plan is for you crowdfunding helpers who want to make more money for your efforts. 

Here is the IndieGoGo site
https://www.indiegogo.com/projects/motorwalker-helps-the-infirm-get-around-easier/x/11147971#/

This crowdfunding site has 3 levels of funding - $7, $47 and $277. 

For one low price of $15 you crowdfunding helpers can lock in rewards for your efforts of
$1 for each $7 funder you bring to me, 
$10 for each $47 funder you bring and 
$40 for each $277 funder you bring. 

Please be sure to ALSO go to the Indie site and send $7. You must take that action as well as this $15 action in order to lock in the rewards listed above. 

This reward program has a GUARANTEE. If you send me both the $7 and this $15 and you take all the actions you feel will bring supporters to my Indie site and NO ONE funds me, I will refund your $22.
