It might be costly, depending on how much link authority you want your first tier links to have. Ideally, this method is great for boosting the amount of juice that your backlinks pass to your money site? How do you plan to build links? If it costs more than 25% of the money you spend on the links themselves, I wouldn't do it.
Basically, if you spent $100 on backlinks, only spend $20-$30 on building links to your tier one.
