Can you recommend me some? 

Knowing your reasons can help tailor advice or agent recommendations. 

Also are there any recommendations for this type of data from sources other than Airdna?

I, and likely most people on here, would recommend finding a mentor in your area that has sor hands on experience with REI or property management.

I have recently joined biggerpockets after reading multiple books that recommended me here.Thanks a lot for reading my post and may God bless the reader & people that have taken an effort to provide me with guidance and help here.

If you need to know how to find them, one recommendation is locate people who have bought properties for cash in that area, then cold call them to see if they're looking for more.

I hope this recommendation helps your search a bit! 

@Claudio Garcia ZunigaBe careful of scam website when applying for a EIN online.Once you open up business accounts, apply for a credit card - I recommend the Chase Business Ink Unlimited. 0% APR for 12+ months.

Not sure I am allowed to post recommendations to service providers on the forums directly.

Quote from @Joshuah Baker: Good advice from David, but I recommend starting the other way around.
