Photoshop action - Need creating to include batch save

I need an action creating to work in Photoshop CS6 running on Windows.

I have mockup files containgin smart objects. The action ned to automatically import an image, apply to the smart object updating the main file and then save into a designated folder. Repeat for all images in a set folder.

I created a basic action myself which works fine but I can't get it to save the final images using the Batch manager in PS. happy if you want to create from scratch. This doesn't need to be overly complicated and should be a very quick job for someone qwith better understanding than me.

I have other mockups of different products, the prioces is the same for these but design size may be different so I will need to be able to edit the action to suit these if at all possible.

I can supply sample files upon request. Just been informed this may need a script to complete properly, happy to discuss.
