I am looking to create a Product customization tool in PHP. This tool will allow the user to create his own Customization to a predefined Mobile cover. I already have a Mobile cover image and I am looking to allow a user to write 3 characters which will be written in a circle called as monogram with a background color.
I am not sure how to proceed ahead with it. I am looking to dynamically create image that is placed on the Mobile cover in such way that it looks its part.
here is the link to a sample image which would be generated

I am looking for way on how to approach it and which php image handling libraries should I make use of.
