In short, yes it is.
But you will always be up against people who do have IRs, even for VFR jobs. And jobs that require IRs will generally always pay more.
PDG and WPD are a couple of operators who do a lot of power or pipeline surveys so they often employ pilots without IRs. Heliair also have pipeline contracts (although I suspect that those jobs would go to their current or ex-instructors).
So is it possible? Yep. Is it easy to find that illusive, well paying VFR job? Nope (because you are up against an awful lot of competition).
