Hi Luis, this is really great.
Here you have an idea: Many agencies with non exclusive content like photodune and Creative Market arent avaible in SP. why dont you create a "Customize your agency" We select the image from our SP data base and manually can insert revenue.
And other sites with exclusive content like W61 we can upload thumnails and manually insert revenues. It will be perfect for take all sites in stockpermorefer while you prepare the site for them.
