What could be an idea is this. If you ever see any public service jobs they always advertise a range of salries for the same position.
Captain C525 - 45-52k depending on experience. I think thats fairly representative considering what that lot in Cambridge are paying.
Typically 45k for one of the (or a) more experienced B200 guy(s) who you have had to type or £52 ish for a grey haired old git who's typed with CJ time and has got a CJ inside a horseshoe tattooed behind his ears....
Also
Type rating preferred or provided for an exceptional applicant.
The wording of this last sentence will reduce the hit and hoper CV senders who think that because you have placed an advert in Flight means that you have three days in a row to peruse CV's
One other consideration is an optional signing on fee of say £1500 for type rated people who should they leave within two years have to pay it back from final leaving salary. Its just enough to focus peoples mind and little enough to be worthwhile doing as opposed to handing over £15,000 to June Spencer and the Hilton at Wichita!
Besides you could always clone Barnesy another time , I'm sure there was three of him running around last summer.....
