How about letting your employer do it?
Whilst it is understandable that unemployed pilots may seek to make themselves more attractive to the more rapacious airlines it is a terrible betrayal of your fellow pilots to volunteer to pay for a genuine business expense that should ALWAYS be borne by the airline.
In my experience buying a type rating seldom if ever makes the difference in gettig a job - most companies want experience and a bare rating does not provide that. Those companies so bloodthirsty as to be swayed by such a self-destructive ploy are the last ones you'd ever want to be employed by anyway.
My advice, have patience. It will come along, as it did to all of us in work at present. DO NOT SUBSIDISE THE AIRLINES LIKE THIS. PLEASE!!!
Remember, in this job we always have to be flexible, but there's a huge difference between leaning forward and bending over. And NO EXCUSE WHATEVER for volunteering to provide the lubrication.
Please don't be so selfish as to sh!t on the industry (and the rest of us) like that...
