any suggestions on a software program that will calculate foundations for ground signs? Looking for information to design sign foundations that will include wind load calculations.
That last statement is the key. Hire an engineer or run the risk if something goes wrong, it's all on you.There is this:

in conjunction with : http://www.amazon.com/Engineering-Sign-Structures-Introduction-Analysis/dp/0944094309
But remember, you should only use it as a guideline. If you do it your self, and something happens, a lawyer can come back on you. There really is no substitute for a hired professional.
Here's an excel macro provided by Murdoch Engineering. Great tool for estimating and then use them for the stamp/approval. Simply fill in the yellow areas and it calculates for you. Iirc, they have a brief tutorial on their website for it.
You understand that if you put your name on that and file it with the city it becomes a part of public record, and you are responsible for anything that happens from the time the sign goes up until either you or the sign are no longer around.
But yes, that appears to be a very legitimate spreadsheet calculator
