You need a PHP programmer

PHP is required for remote development.
The following customization is required for the crowdfunding engine Goteo (Testo nascosto):
1) redesigning the homepage to look like Testo nascosto (will also cause footer and header changes for other pages)

(2) development of paid membership levels to allow users to set the following restrictions:
Basic Membership - you can create 50 projects at most - Free |
Advanced Membership - you can create 100 projects at maximum - $39.99 / month |
Pro Membership - you can create an unlimited number of projects - $49.99 / month |

I mean. The client will pay a fixed percentage of each successful project (this functionality is in the engine) + monthly for the membership (this must be developed).

(3) Integrate Stripe payment system to allow payment processing and automatically distribute fees between the site owner, the site sponsor and the payment system.
At the moment, the engine has implemented payment acceptance via PayPal.

For the project, only an experienced PHP developer is needed (possibly in tandem with a layout designer).
