Buy
Everything of mine you can actually buy.
I have more ideas than years, so some of them are for sale rather than sitting on a shelf. The tools are ones I built because I needed them. The workshops and kits are what I know, written down. The paintings and the clothing are on their own sites.
Nothing here goes on sale, and nothing here is discounted. The price is the price on the first day and on every day after it.
Business ideas
8 for sale
The dossier is the full working file behind an idea, sold at a fixed price to anyone who wants it. It carries the market read, a worked cost model with the assumptions on the page, the first ninety days and the honest reason I stopped. A few of these can also be bought outright, but only where there is genuinely more than the dossier to hand over, which the idea page will tell you plainly.

Workshops and printable kits
14 audio workshops you listen to a step at a time, 10 printable kits that go with them, and companion workbooks for each. There is also 1 free download if you want to see the work before you pay for any of it.
Art and clothing
These two live on their own sites, because a painting and a shirt both deserve better than a row in a list.
