Welcome to a world of strife, a world free of women, drugs and booze because from this point on, all you will be able to afford is bun kebab. Unfortunately there is no magical solution to your needs, nor is there any mythical unicorn of a denter or mechanic who will do everything you want the way you want and in the time you want.
Throw your watch away and set fire to your alarm clock, time no longer has any meaning in the world of denters and mechanics, deadlines are just lines.
First off, show your car to a denter of repute after you get recommendations from people who's work you have seen. Ask him to let you know what the condition of the engine bay is and whether the engine needs to be taken out for any work or addressing any rust or rot.
This will to a large extent determine your time line is:
Time Line = X
Time Line if Engine is not removed: X + 3 +/- 2 (months)
Time Line if Engine removed: {X + 6 +/- 2 (months) } + more than or = 2 months if electrician is needed
If mechanical work is needed but the engine does not need to be removed, get the mechanical and all other work done before sending the car to the body, you dont want the mechanic destroying your newly finished paint. Also please bear in mind, ideally do not remove anything off the car which doesn't absolutely have to be removed, open it up as little as possible, unless you have someone from Motomachi to put it back together for you.
Good Luck and Godspeed,
Life as you know it will never be the same again.
