1)For your big ticket product you could create a course that teaches people exactly what to do to start their own business in the niche - for example, how to start a dog training business.
You would want to make it completely self-contained - it would give them everything they need to start their own business - including all the training, all the procedures and techniques, all the paperwork - everything.
In fact, you could probably charge $10,000 for something like this instead of $5000 - but at $5000 it is a steal - and you want the high-ticket item that you are using for the top of the sales funnel to be somewhat affordable.
2)You could create a complete program that shows someone how they can take an existing offline business and duplicate it online - show them how they can sell all over the country, or the world - instead of just being limited to their backyard.
You would want to make it easily cookie cutter and duplicatable.
And keep in mind for something like this you can outsource some of what you would need to include - for example, if you need a course that will show them exactly how to set up their web site, buy the rights to one and include it - or better yet, improve it so that is especially adapted to their niche.
Now you see that there are many things that you can produce in your very own niche that can be sold for $5000.
Now that you have come up with this product, idea, of course the next step is to produce it.
