Build a Non-Profit Website with Secure Donation Collecting

We are starting a non-profit to empower youth and support a community in Haiti through programs and initiatives. I purchased a URL at SquareSpace but am willing to build the site at a handful of easy to use hosting platforms. We are looking to build a website that really promotes the work we do, shares our stories, and communicates to a community of people that will donate to the non-profit. I am looking for a site that would have the following... A homepage that has the mission/vision a part of it and links to... - Our Story - Would have pictures of the program and a story about how the program got started... - What's New, Upcoming Event, and Current Projects - With ability to easily post pictures/videos, update and add new stories/upcoming events. - Former Projects - Ability to post pictures and tell the story - Blog - A place where we can blog as needed about an event, a travel, or tell a story - Donation - A place where donations can be easily added, we can transact, and we can automate e-mails back to donators via paypal or our bank. We will provide you all the beginning content. The concept is to make this a very simple and easy website to use that people can navigate and engage, to drive donations. Also an easy implementation so we can update stories, blogs, add pics/videos, and events. At appropriate places, perhaps the ability to see and/or connect to Twitter/Tweets and Facebook accounts. We have a logo already completed and are interested in someone that can build this simple website with colors of Haitian colors. Interested to hear your experiences in building such a site, seeing some examples, knowing you can add secure donation collecting, and how long it would take.
