1.5 inches .. thats a Font size of 108 (72 pixles per inch)
And Really, any font that you want that is accessable via the internet is possible. I helped Erick find the font he used for making the decals by using a Free Font website. So really, He can make the font anything you wany it to be.
And webbing is completly possible for you. Basically, if you want to, you can make the appearance of the emblem, slap it onto a JPG and attach it here, and I'm sure Erick will work something out with you.
