Premium Visa: Funds

Hi,

I am planning to apply for the Premium Visa to work remotely from Mauritius for a year. One of the requirements is: "proof of funds (bank statement or bank attestation) to meet the cost of stay in Mauritius (minimum amount of USD 1500/EUR 1300 for monthly expenditure per head and minimum amount of USD 500/EUR 400 for each dependent below 24 years old)" as listed here: https://www.edbmauritius.org/premium-visa

Does this mean that you would need $1500 x 12 = $18 000 in your bank account before applying OR would a lesser amount including proof of income (employment contract / 3 months bank statements / freelance agreement) be sufficient to prove that you can sustain yourself during your stay on the island?

Also, does the amount of $1500 include accommodation, e.g. if I rent an apartment for $700 per month would I only need to prove that I am receiving or have access to an additional $800 per month to sustain myself?
