Not a very sensible question, really.
It doesn't cost you anything but the trouble to fill out their forms, so instead of posting this, you could have already done that.
Finding a job as a FO, especially with low hours, is not easy, so it will take you quite a lot of comittment.
As far as my experience with Rishworth, Parc, Sigmar, etc. is concerned, they will send you some offers now and then, but with low hours and no PIC-experience, it will be difficult. Of course it is still worth trying.
My suggestion is, that wherever you are now, just hang in there and get more hours first.
