This is exactly what we are working out when we get first get into contact with you. The first step is to figure out your difficulties and whether we can solve them. We are humble enough to admit, when a situation exceeds our current capabilities, and are happy to forward you to trusted partners.

It doesn't make sense to work with somebody we cannot truly help, does it? And then, of course there come our guarantees into play. Should our work not reap the promissed rewards you pay $0. (This has never happend, by the way, just saying.)
