Yes Janet … once you confirm your garden meets the Pollinator Link standard – 1 source of water, 3 of food and 3 of shelter you can register for $20 which helps pay to expand the project. You contribution will be acknowledged with Blue-banded Bee on Google Maps and a sign for your fence. https://pollinatorlink.files.wordpress.com/2016/10/pollinator-link-certification-form.pdf
Pollinator Link 
I would like to know if this certification offers a sign (to purchase) that can be placed in the garden to identify the certification
