Starting an one stop shop for people who want to move abroad/migrate and helping them with visa options. Our focus would be investment/startup/skilled/ancestry visas with relocation services + help with taxes. Also how would I monetize this aside from the referral commission cut?
I'll give you an unconventional answer. The best way to know which one is better, is to try both. Yep. No point starting niche and then going broad, or starting broad then going niche. Just invent an alter ego for both, until you realise which one is better. You will have to work twice as hard, but it will be worth it in the end.
