No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
I think you will need to offer a bit more information here, such as:
Length of credit history and AAoA
Personal cards (what banks do you already have accounts with?)
Debt-to-credit ratio
Applying as Sole Proprietor with personal guarantee or with an EIN using the business's established credit
Credit scores are not always the only thing that will get you approved. The lates and collections will also be taken into account depending on the age, severity and status of those collections (still outstanding, paid, settled etc).
Almost anyone can get business credit.
Why do you have to PG? Do you manage a responsible bank account for your business?
Alternative lending is where you should be focusing. What bank is doing business with you now?
