Consulting vs Digital Product?

I have a good problem...

I run a newsletter for a niche audience and is growing fast (700 subscribers now, 100 this month). I provide free information; no subscriptions. I use the Substack platform.

My problem is an issue with creating a product (one-time fee structure) vs hourly consulting

People know my skillset and want a piece of it. They want 1-hour of my time as a consultant to review things. I initially charged $125, then $150 and now just did one for $200. No one batted an eye paying that. Success!

I can package this knowledge up into a digital product (e-books, some videos, checklists, etc) so people can do my skillset on their own. Albeit not perfectly but at least somewhat.

For the product, I could probably charge around $50-$150 one-time.

Pros of consulting:

• Exclusive skillset. A few in the industry can do it right. I am one of them.
• High hourly rates
• Ongoing opportunities as my list grows

Cons of consulting:

• Trading time for money

Pros of digital product:

• Set and forget marketing
• Scalable

Cons of digital product:

• One-time fee
• No recurring element. A single customer may hire me multiple times for 1-hour consulting but with the digital product, try to learn themselves

What would you do? There will be a subset of people who will always hire me because it's not easy. But a large group will buy my product and try it themselves.
