There are two mandatory costs and one optional cost associated with a TitleLeaf site:
Mandatory: One-time setup cost
Example: The standard TitleLeaf theme customized to a publisher's corporate image incurs a one-time setup cost and takes 3 months to complete.
Mandatory: Monthly subscription cost
Example: If a publisher has 1000 active titles, each with 2 images and 1 "look-inside" excerpt per title, they'll need 8 GB of disk space. That corresponds to the 15 GB plan.
Optional: Maintenance cost
Example: If a publisher would like to outsource site maintenance, they can engage the TitleLeaf team for as little as 15 minutes per month.
