Hi, I have a certain font that I really like, but it's a corporate-designed font and nobody can use it but the corporation.

1.) Is there a font creation software package that will allow me to input JPG images of this corporate font, make subtle changes to it, and create my "own" font?
2.) Is there anyone on this list who can do this for me, for not a lot of money? :-)
3.) Is there copyright law I can read which describes the legality of modifying and re-using fonts?

I've looked hard for a suitable replacement, but nothing comes close, especially with specific styles (numerals, small "s", small "l", small "g", etc...)

Thanks,
JL
