potential??

[dooie]

ok guys so i just wanted to post up here with a few questions and asking for a few tips to get started. im 24, about 187lbs, 6"11
i really want to do a comp next year, but i know i dont have enough muscle mass on my frame (it has been very hard playing football) i would like to try put this on naturally for aslong as possible, i eat well (i do need to get my diet properly sorted) and i train very hard.

i train one body part a day, workouts usually last for an hour to 90mins
chest
back
legs
shoulders
arms/abs

i will post my diet up within the next couple of days.

is a bodybuilding comp realistic for me next year(natty)? i would like to change my diet to put on mass but i dont want to gain fat!
i havent really stated many questions, but perhaps im doing something wrong (training wise) i would just like to put as much weight on naturally as possible.

your help is much appreciated!
Ps would anyone like to coach me over the internet?
