Anyone here paid for getting their business credit increased?

Hi!  

I have been approached on getting my business credit increased for $3500 for the year.  They promised first year 0 interest for loans anywhere from $50 to $250k with their advisors.  Anyone have experience with increasing their business line and utilized this? I have excellent credit but certainly have never paid attention to the business side.  They got some big name investors endorsing this but would like to hear from other's advice and experience.
