Or, you can register on this web site:
which is owned and operated by Harry Dunbar, who's a tile setting contractor in Barrie, Ontario that specializes in showers. Harry has a DIY Q&A forum on his web site for newbies to ask questions and get advice as they construct and tile their own showers.
And Harry doesn't charge a dime for his time.
The problem with any kind of DIY TV program or course is that you learn what they teach you, but when it comes time to do it yourself in your own house, you discover that things aren't the same as they were in the TV program, and you're uncertain as to if and how that changes the gameplan you've been taught.
If you have a digital camera, you can get onto any DIY tiling web site, like Harry's or John Bridge's and post pictures there of your situation so that any experienced tile setter can tell you what your options are in that situation.
If Donato Pompo is widely recognized as "one of the industry's top men", why don't I see him earning extra money for himself by endorsing products for Mapei, Flextile, Custom Building Products, etc. just like Bob Villa and others did? (Not saying Bob Villa knows squat, but he's smart enough to milk a cow when he sees one.)
