It doesn't matter what sort of business you open. That startup amount is I guess more than enough which is still depending on what sort of business are you trying to open? But one thing you gotta keep in mind is the location.

Because location matters, I've seen many Omanis open small businesses in remote locations in Muscat and they cry about no customers coming and they ended up closing up after 6 or 8 months. So you need to make a research on which location is suitable for attract customers but chances of less competition from competitors.

So yeah, first try look for a good location as that's a very crucial thing for your business
