Well, yes, someone good at photoshop can do it, I suppose...
But I can give you the .psd files I used to create both the border and the signature. That would be easier... And you can also change anything you do not like easily there...
It's a bit of a mess though... I did not work very clean... But I am sure someone with photoshop skills can easily figure it out.
Thanks for the payment. I'll send the files soon through PM.
