Just to reiterate. You don't "ask" for freelance pay. You negotiate it up front.
It's amazing how many writers will agree to do something without asking how much it pays, though.
In this climate, I understand the hesitation. There are so many 'writers' that someone young is afraid of being rejected for discussing money.
I got over that fairly quickly. It also helped that the editor of a paper where I was an intern advised me to inquire about kill fees and rates before putting in work on any ideas I pitched.
Normally, what I do is pitch the idea first. If they like it, I send a bit more detail on the story and how I intend to complete it with my desired compensation at the conclusion. You're not a staff writer, so this is a business arrangement, my friend.
I never received counteroffer at first because I was low-balling myself. Now, I'm pretty sure most editors are accustomed to negotiating a lower rate, so I start at a best-case scenario. Then again, I haven't sent an offer in a while since I'm pretty secure with the places where I am published. Whatever secure means.
For the most part, if they like your idea, then they'll work with you on pay. No need to be scurred.
As for your current dilemma, obviously we don't know the nature of your relationship with this editor, or how friendly the two of you are. Don't be afraid to burn the bridge. Be firm, but respectful.
But if you have another idea and a proposal prepared, maybe you can send that along with compensation details. You're not an intern for him, and even if you are young, you shouldn't be working for free.
Best of luck. And congratulations for not posting it on Bleacher Report first.
