Is there anyway to download unwatermarked comps as a self-employed designer?

I can see that on an Enterprise account you can download unlimited unwatermarked comps, but what support is there for self-employed designers? I'm a film poster designer who needs access to high-res comps whilst presenting multiple options and rounds of posters to a client. However only one poster will ultimately be picked to go public, so only the stock imagery in this poster needs licensing. Is there any subscription available of this nature?
