The HR person at DHL Air, East Midlands Airport, is Ginny Hambly. She can tell you whether DHL are going to be taking on pilots. Sometimes, they sponsor people without 757 ratings. With your hours, you might do very well with them.
There is the possibliity of being based in BRU, too, if that is what you want. Theoretically, DHL Air's base is EMA but they are quite amenable to Brussels, because most of the work originates there.
New rosters will be 8 and 6 (or 9 and 5 as necessary). This will mean less flexibility but more time off in blocks of days. Depends what lifestyle you want.
Good luck. Enjoy!
