Thank you for your reaction, but I think we have a little misunderstanding.
I don't want to add alternate options, it shouldn't be a variable product. It should be a simple product. I'll try to explain, let's say I wanna sell a table. But the table is completely custom made. So it depends on size, materials, finishing, paintjobs etcetera, just what the customer wants. I can't say anything about it, except that the minimum price for a custom made table is €500.
But, I also have a table which is already finished, which will cost €600. These are two simple products, without options or variables added in Woocommerce. The finished table should say 'Price: €600,-' and the custom table should say 'Minimum Price: €600,-'.
So what I mean is that with every product you have the choice to give it 'Price' or 'Minimum Price'. Without having to add variables, options or price additions.
