Hi I am a single parent...I read a few different post on the back-door approach.....they go a few years back... 1) Can I person still obtain a high score without using a personal guarantor (after incorporating)? 2)Do I have to pay Dunn&Bradstreet $299.00 or $399.00 or whatever, to get into there system? 3)I read one post that stated using Staples,Office Depot, Kinkos, Home depot, Lowes, and a few others would give a high score when payed properly without using a personal guarantor? I simply want to be able to survive without doing something illegal like this alternate credit file stuff that so many say it legal. Can those of you please help. thank you, kev
