Agree with Tepford. Do not cut. Once you lose the fat, you'll just be an un-muscular boney twig.
You don't need a trainer, some of the best trainers in the world have posted their programs on this site and will answer your questions at no cost.
As far as diet, slowly clean up your diet, so that 90% foods come from quality source ie. meat, potatoes, rice, veggies, etc.
Do that for two years and you'll like the result.
