Need advice

I am going to be doing a large scale painting for the hospital that I work in. It’s a painting for the oncology unit that I work in and will hang next to the bell that patients ring when they finish chemo. The canvas will be quite large- 6x7 feet, so I will need a lot of paint. My question is- can I use Benjamin Moore paints? Originally I wanted to buy Liquitex acrylic paint but someone wants to donate Benjamin Moore paints. Since this is a project that we are funding via donations, I don’t feel I have much of a choice. I’ve just never painted with “house paint” on a canvas. I’m a little nervous about it. Anyone have experience with this?
