If you are interested in doing a figure show and want to get a trainer I would suggest getting a nutritionalist. The diet is the tricky part of any show. For the training aspect you can get a ton of info and help for free on this site or
http://www.figureathlete.com/index.jsp (aimed towards figure athletes) Not to push you away from this site , but I'm sure you will find more people over there who have been through or going through.
Like Dave said , starting a journal ( here or wherever) is a great idea and very helpful.
