Joe Hall was cool enough to make a JSON-LD Schema Generator tool for SEOs. The tool is very easy to use, you pick what Schema structured markup you want for a specific page and then fill out the form to the best of your ability. When done, copy and paste that code into your source code for that page and presto - you got schema markup on your page.
Here is a screen shot of the tool in action:
The types supported are local business, product, person, organization, event and web site, with subtypes for many of those.
You can access the tool over here.
