@Katie,
Currently, I know that both Antigua and Barbuda (https://antiguanomadresidence.com), and Barbados (https://barbadoswelcomestamp.bb) are the two islands that offer remote worker visas. They cost between $1,500-$3,000USD (depending on family size), and are valid for one or two years. Many hosts, and other business owners have made requests to the St. Lucia government to establish a similar program, but no action has taken place. However, I am seeing that people are informally taking up temporary residence on the island by remaining for the duration of a non-visa required stay (six weeks), and then applying for extensions (up to six months). This is actually cheaper than the formal programs on the aforementioned islands. So, St. Lucia is missing out on much needed revenue.
In fact, I have two direct bookings for long-term stays scheduled to start in the next few weeks. One is from the from the UK and the other is from the US. There is a local vacation rental association for hosts, and I frequently see requests from local realtors or individuals seeking long-term stays for people who are relocating, working, studying or vacationing. Since I am new to the group, I don't know if these requests are more, less or the same as pre-COVID.
I need to be more organized like @Robin4 and @Ann72, and keep a proper running tally in a spreadsheet.
