Hello,

There are many stock-photo / image sites that allow you to purchase quality images for reproduction (be it signage, catalogs, flyers etc.). I'd recommend the following:

https://www.shutterstock.com/ and https://www.gettyimages.com/

For Freebies, you can also search: 

https://pixabay.com or https://www.vecteezy.com

After you have creative assets, working with a qualified printer with in-house design capabilities can make the whole process easy. We offer these services for many small businesses, as well as our corporate clients. To learn more, check out our websites: 

https://www.artisancolour.com/ or https://artisanhd.com 

Cheers,
