I'm 5'8in. 75kg is my target weight (I'm aiming for a sub-4h marathon if I get under 80kg). I'm 95kg right now (skiing was good for beer and food).
I don't know what time scale is appropriate.
From my experience I know I can sustain 0.5kg a week weight loss for prolonged periods (by increasing exercise and not overcompensating with too much extra food). When starting to exercise I usually have a 4 week plateau where fitness improves and body shape changes but weight remains static (as the body loses fat but gains muscle).
Amateur.

10kg at 0.5kg/week = 20 weeks + 4 week plateau = 24 weeks.
Now + 24 weeks = August 7th, so 19th July is not out of the question, especially if you make quicker progress than I tend to. Good luck with it!
