Recommendations for an Orlando tax office?

My US Citizen husband can’t find someone who knows how to correctly file his taxes.

We got married in Florida and are in the early stages of the CR-1 visa, while I am still living in Canada as I always have. We do not support each other financially or share any accounts.

For this reason he wants to marry filing separately but we have heard different things about filing separately vs jointly, about writing NRA vs getting me an ITIN (I’ve never worked in the US), etc. It has been very confusing and frustrating.

We just really need someone who knows what to do in this situation.

Thank you in advance, sorry if this isn’t the right community but I’m hopeful that someone in here will have been through this!
