Most of us are self-oriented to such an extent that we can say that everything we do is for some selfish reason. It's natural. You and your prospective friends both have their own selfish reasons to be friends. You want their friendship so that you get a partner in doing things that you value(creating a website for a charity) and they do the same (watching a movie or hanging out together for fun). So, you need to meet with people who have values/interests similar to yours. Now, most people want to do fun things so it is easy to find such friends. Not many want to WASTE their time in things such as building a site for charity, so it is difficult to find such friends. Personally, I have different groups of friends - friends to hang out with, friends to discuss ideas with, friends who are always available when needed in emergency, etc. My suggestion : meet with people having similar interests. Attend meetups, events etc.
