Project Page For Plumbers

Hello I was wondering on what people do for clients where they want to have a page full of projects they have done including a gallery. How they display the projects with a gallery.

Can everyone please post up there Ideas on this as I am going to build a website for a plumber and they have over 20 projects they have done and they would like a gallery attached to each of them.

I am thinking of using the NextGen Gallery plugin but dont know how to display the page / portfolio of projects
