Add text to approx 100 images

I have approx 100 photos of items that are sold online. These are mainly metal, engravable items such as hip flasks, money clips, etc. I would like some text, such as 'your item engraved free' added to these items. The text needs to look as though it has been engraved onto the items.
The photos have been taken at different angles so you'll need to account for perspective. Please see the attached image.
I would like the job completed in the next 10 days.
