It took me 4 months trying out 3 different methods and the one that ended up working is now scalable and easy now for me to deploy.
Any chance you can document this solution somewhere to help the community out? Or are you looking to "sell" your knowledge? 
Given:
- the time, efforts and resources I had to put into this
- the value for people to get back access to thousands of euros or dollars (that's mostly bonus since I guess few people buy BTC at $45,000 to get locked a few days later... it's rather people that have been locked for years and have generated profits as long as we're at an ATH)
- my need for honest, hard-earned revenue (I'm not a philantropist billionnaire)
- how much other people like Dave @WRS charge
...it wouldn't make sense for me to give it all away for free right now. Don't get me wrong, it's "just" software and hardware and if I was in a very different financial situation myself, I would consider uploading my scripts and instructions to a github repo and let everybody use these tools to help themselves.
But the way I see it, I'd need to crack a few valuable wallets before this happens. Also, some people will never put together the software and hardware required to run it because they don't want the trouble.
I know there are other last resort options when it comes to unlocking wallets and people are welcome to try them out.
But I do believe there are niche situations where my service can be more appropriate.
