Designing a Website for a Non-profit Organisation

I would like help towards putting together a website for a Non-profit Organisation called the D'AMUGE Fund. Our club started last year in upstate NY at Clarkson University and we are looking to expand our services beyond a local level. Our mission is to raise funds to provide the youth of Benin, West Africa access to a better education. We believe that a well designed website will allow our organisation to progress significantly. On this website we would like to be able to upload pictures, videos, have a blog, show updates on the front page, have a pay-pal account and have an option for people to make donations online. In total, we are expecting our website to have 8-10 pages. We have a tentative deadline of September 16th to meet. It is very likely that after we establish our website we will be making periodical updates to the lay-out. If this is the case, we will solicit the help of the person that first helped us establish the website. We currently have a logo but we would like it to be more professionally done.
