The acquisition of advertising/birthday greetings/etc. ain't my department unfortunately. I could probably send you in the right direction, however, to make that dream happen (Though I don't seem to recall ever having done a graphic/picture for a birthday greeting). You really do have great ideas, perhaps you should look into coming to work with us. :)
By the way, if you feel like catching a Beavers game sometime this season, I can hook you up. Not only will you be able to watch the game, but you will also be able to enjoy my dyn-o-mite skills on the new video wall they have at PGE Park. If you want Thirsty Thursday, that's gotta be a few days in advance...
