There are too many "Certified" in this business! It seems to me that Certified Marketing Services was the old name for Certified Reports, which became the 'purple portal' of Market Force, though I could be wrong.
If you are uneasy, don't play. There are plenty of legitimate companies to work with.
That being said . . . every time you write a check you are handing out your bank account number and routing number in addition to your signature. Yet you are not responsible for unauthorized distributions from your account. In fact I suspect that handing out your bank account number is safer to you than handing out a PayPal or PayQuicker account information or depositing a check.

So the question in my mind is did you find this company or did they find you? I just don't think that 'Certified Marketing Services' has been the name of a mystery shopping company in some time so I would wonder if you are on the first 'trust building' stage of a con or scam.
