Anyone on here fancy setting themselves up as an internet monitoring consultancy for the travel industry? You would have no problem getting BA to pay you £20k pa for a weekly '1 page of A4' summary of what is being said about them online, emailed to key managers. Get a few other players to do the same and you should be able to get to £100k pa income without much difficulty and with minimal overheads - plus you get to read FT all day!
I'm relatively serious - beyond the lawyers, IT consultants, City directors etc on here there seem to be plenty of others who knock along on sub-£30k and who could make a far better income for themselves for less work by putting their FT knowledge to profitable use.
