This problem with micro-nations is by far best solved by advertising and just getting more players. It shouldn't be costly and there are probably a lot of options that are close to free. I am working closely with India a small nation and they are very happy with their 80 or so managers. It is only the really tiny ones that have an issue. Mind you Pakistan was supposed to be on the brink of extinction and now has 37 äctive"teams, Senegal is up to 41 but South Africa has only 15 and UAE is down to 14. They do go in cycles.
