What is your experience, and what are your qualifications?
If you're looking to build time, just write it in your logbook.
If you're looking to build experience, that's a different matter. Your personal qualifications make a big difference in what you might be eligible for.
You may wish to keep in mind that most companies serious enough to be flying turbine equipment aren't looking for people to hire in order to get them some "time." They're looking for dependable sincere professionals who want to provide good service to the company.
Also bear in mind that a lot of professionals are seeking work right now as a means of surviving, feeding their families, and of living. In an industry where things have again become scarce, folks flitting in and out to build "quick time" can have a bit of a grating effect. Jobs aren't as easy to come by for now; it would bother me as a professional to know that I lost out to someone just looking to build some "quick time."
