this is old  tried and true method of simply having you pay them to get credit cards .. there is no need to pay for this service.. unless you want to of course.. there is no magic bullet ut there that is going to give you credit and financing unless you actually qualify for it.But zero interest credit cards are used by some to do rehab and then pay them off issue is though your fico score drops like a rock the second you take on all these CC.Also starting out there is zero chance of getting any kind of business line of Credit that is unsecured.

Some of the simpler asset protection solutions would include the following:  having max funds allowed in qualified retirement plan or IRA rather than personal as retirement plans are exempt assets in Federal and most state bankruptcies; investing through an annuity if your state (Florida and Texas for example) exempts insurance policies and defines annuities as an insurance policy; taking advantage of maximum homestead exemption in your state; use of corporations or more popular LLC or Series LLC to limit liability to the entity holding the asset; reasonable liability insurance if available; separating asset ownership from asset management; etc.I can design a simple, cost effective asset protection strategy of up to about $5million with little cost IF the individual resides in Texas or Florida.
