Would a realtor help write an offer to a wholesaler for a newbie?

[Andrew Robbins]

Apologies in advance for stupid question.  It's a little daunting for me to write an offer for the first time on a wholesale property.  Don't want to make expensive mistakes.  Would a realtor help guide me through the process of writing the offer the first time, so that I'll know how to do it in the future?  The "what's in it for him?" part is that he's going to get the commission when I sell it in six months.  Am I being naive?  If so, is there a foolproof guide I can get somewhere to learn the in's and out's of making an offer?  Thanks!!
