I think it would be very easy to do yourself if you are remote worker for a company.
In Netherlands I did the complete process including garnering docunents in 20 minutes and got approved within a week.
All you have to show apart from passport and photograph is proof of the 500K in a bankaccount somewhere in the world, work contract and if not mentioned in the work contract a statement you can work remotely.
If you have an own company it is a bit more tricky, but also possible to do.
The soft power options are a bit more difficult because you need to collect the necessary papers.
