First, welcome to the site.
And I love the goal. And I hate to dash any dreams, but you seem to be asking how to spin straw into gold. I just bought 132 1988 cards for $3 plus shipping. They just don't pull much cash. Williams's cards from his playing days are hella expensive, which is why I own exactly one. I don't really have any suggestions, other than to save your money, buy when you see a good deal, and don't expect to be able to essentially trade even an entire 80s set for one decent 50s Williams. Maybe some of your Tiffany stuff, which I really don't know much about, could garner a few more dollars?
Either way, I hope you succeed. Good luck.
