customization of Wordpress plugin

Avg Bid (USD)
Project Budget (USD)
$30 - $250

Project Description:
I need to have a little customization to the Fundify WP plugin which may be found here:

These are the customizations i need:
- rather than working based on reaching a certain goal (money) it should work based on reaching a certain number of pledges (set by the project creator)
- the project starter should set a minimum number of pledges (after which the project is funded) and a maxmimum number of pledges (which if reached the project is closed and cannot be backed anymore)
- there should only be one single reward per project (this shouldn't even be a customization, it is a matter of allowing only one reward when entering a new project)
- there should be the possibility to add x custom fields in the project page as well as in the start project page and make those fields searchable in advanced search page

The customizations should work with the fundify theme as well as the extension of easy digital downloads which is needed to have the original plugin working

Please let me know if you need further information.

Skills required:
