Mashreq Neobiz is the simplest one. Will take you about 3 weeks and we have to apply online (They don't accept in-branch application). Make sure you have your CV, corporate stamp, company history, website, past bank statements, etc.
Better to buy your own printer actually and rent a car as you'll need to do a lot of back and forth.
Commercial Bank of Dubai has a new product called CBD Rise Starter which is aimed towards small businesses in Free Zones. You'll need to visit multiple︀ different branches as some won't have any idea of what this is and some will︁ tell you that you need an account with them for at least 3 months before︂ applying (This is a lie, they are just misinformed).
ADCB has the SmartStart account. You'll︃ need to visit multiple branches and someone will end up giving you the WhatsApp number︄ of someone who works at the main corporate center in Sharjah. From there, it takes︅ 3 weeks and it's easy to open if you have all the required documents.
Good luck!
