@dxbkk - Is your UAE business setup plan one for the long-term?
@rowena has already given you the basic input on 'legit setups' that should do for an "easy" local corp.bank a/c opening (though I insist on forgetting
Emirates NBD at all costs nowadays, for a variety of reasons I don't need to go in detail, FAB or ADCB and even Mashreq/Noor are perfectly fine options). and honesty, I can't see the reasons behind using an
EMI in the UAE instead of a bank (particularly if your answer to my Q is affirmative).
Your total cost estimate is fair (could be a bit higher, though (*)). The better you 'present' yourself (ie, not using a shared co-working office but renting a proper office, preferable in a 'prime' location such as Business Bay or JLT/DMCC), the easier it will be for you (and I daresay quicker). And bear in mind RE prices can always be negotiated lower in Dubai (one of the advantages of their perennial 'inventory glut' magic), up to 50% from asking price.
