Say you sell educational widgets and also another unrelated service, which itself can be split into two. Call it Mulching. Big mulching and small mulching.
You need a page, and very preferably a GROUP of pages focussed on your educational widgets. DO NOT MENTION Mulching at all, apart from in navigation.
Then you need a group of pages on general mulching, with mulching prices, plus page(s) for big and small mulching, with examples.
I hope that makes sense.
However, if your educational products is the main ROI generating business that Home page can serve or mention educational toys.
