To Hire or not Hire

Hey Ya'll

I am really trying to figure out if i should hire a nutrition coach to help me get ready for my first tri in 5 months( a sprint)

I am an avid bodybuilder but have taken a break to attempt this. So i have nutrition down, except not when it comes to nutrition for a tri!!

I also would like to get to about 9-10% bodyfat while prepping for the tri, i am currently at 14%.

Would people reccommend a coach as its not outrageous pricing for a decent one (350 for 12 weeks) or should i take my knowledge and apply it to tri training.?

Any guidance is appreciated. I know i wont finish in top 10 for my first one, but i want to try and place top 50. I am competitive, so i don't know if that changes anyone's opinion of which way to go.

thanks alot!
