I'll stay away from the specifics (as I don't know the first thing about charities in Morocco) but will try to steer with some of the basics:
i want to know how to study the reliability of the project in addition to its possibility of being applyied in reality ?
This is called a Feasibility Study. You'll be able to find lots of research specifically on how to structure feasibility studies in the NFP sector. An example: https://charityvillage.com/Content.aspx?topic=campaign_feasibility_studies_taking_the_time_to_find_out_whether_the_time_is_right#.Vi1k-H4rKM8
i want to know how to convince college students to volunteer for the project ? and how to get them commited to it ?
Should be researched and covered as part of your feasibility study.
If I would put together a workplan of the entire project ? how do i do that ?
Your first step would be a Strategic Plan, you want something high level before you even attempt to get into the details for something on this scale that requires significant upfront investment. An example: http://www.otsmanagement.com.au/wp-content/uploads/2014/05/Strategic-Planning-for-NFP-10-Step-Guide.pdf
How to get sponsors to help with the project ?
Sponsors generally won't be interested in "an idea". Lots of people have ideas. A Feasibility Study and a Strategic Plan would be great first steps to be able to pitch to some potential sponsors and get them involved. It shows that this is more than just "an idea" and something that has passed the rigors of some serious thinking and research (and has been found to be feasible).
