Is there a resource to share. download or purchase Captivate 8 Templates and Themes?

I am a new user of Captivate and have used several of the themes organic to the program but now find them a bit old - although I am getting fairly proficient in creating elearning courses, I am not artistic enough to create my own templates and themes.  Would be willing to pay for them if they are good or simply a resource to share user created templates and themes...??  I very much appreciate any help..  Thanks
