cost of corporate credit building programs: worth it?

[Lance Luvaul]

Hi everyone. I've just setup an LLC to hold property title and have learned that lenders won't (or are likely not to) lend to my LLC without a personal guarantee from me. As I don't want to be personally liable for my LLC's debts, I've started investigating corporate credit building programs that are available out there. Dunn & Bradstreet have one and I'm sure there are others but the one that pops out of a Google search first is the one from http://www.companiesinc.com/

The benefit they advertise that I like best is a more rapid buildup of good corporate credit than if you were to DIY.

Can anyone advise as to how effective these types of programs are? Are they a waste of money or do they actually work? Is the cost worth it or is it better to DIY, and why?

Thanks
