Rewards Credit Cards

I would like to know how did you get approved for the credit card…i
just started my own business and applied last year and didn't get
approved maybe it was because my scores were low…now i have a credit
score of 712 and i currently have 15 Inquires for the past 14 Months
for Experian, 3 for Equifax and 2 for Transunion altogether thus far.
And i would like to know if i should wait another couple months before
applying for another business card. In the world of business credit
application how do i fair with my current status????? And my chances of
approval i just don't want to bum out and just end up with another
inquiry with out approval. Thanks
