If you were to do it make sure it were for one-time publishing rights only.
Publications have guys like us over a barrel. I've done small time freelancing for a long time and the pay gets less and less every year. But photographers are a dime a dozen in the digital age, where all you have to do is send a file, not deal with slides, negatives or professional scans. Stock agencies sell freelancer stuff dirt cheap and get usually half of what the publication is paying, which also keeps driving the price of images downwards.
At least in your case your type of work is much less available than sports and wildlife.
I used to at least make enough to buy some new gear or get repairs once in a while and cover expenses. I keep shooting football because it's what I do, but I pretty much lose money doing it. I've been thinking about cutting back on games, but I don't want to get kicked to the curb altogether. I still love doing it, though I travel a lot less. I don't make anything on wildlife stuff, but I would like to figure out a way to get some return for it to keep covering costs and make a few bucks. But there are wildlife photographers behind every tree basically giving away stuff.
