Routers and switches for a university campus

I am currently writing a report on designing a network for a university campus. I struggle quite a bit with what hardware to choose as I have to pick the exact switches and router models. I have only one router to hold the entire network of about 400/500 hosts. What router would be good for that? Can anyone recommend some models?

Also switches, I will have 2 core layer switches, 6 distribution layer switches for each building, and then many many switches within the buildings as the access layer. Can any recommend any switches for that?

Finally, is it best to go for 10gb bandwidth or 1gb for the switches?

Thanks, I hope I followed the rules this time when making a post.
