I hate to do this again so soon, but I think I'm going to be closing requests again on the 15th. I currently have 14 requests in the queue, and about half of those are ones where I have to go searching for stock to match the requested scene. That can add a lot of time to the process (for example, I looked through over 8000 images last night for just one request. I found three that might work, IF I do a bit of manipulation on them before I start the furry part). I work six days a week at two day jobs, with an hour commute each way, so I only have a couple of hours a day to do any requests, and anything else I want to do with my time. I'm going on a week-long business trip for one real job at the end of June, and if this is the workload I'm getting after a single week of being open, there's no way I'll get caught up before then if I keep requests open all the time.
While I'm at it, I guess I should say that I'm currently exploring my options for stock sources that are permissible for commercial (i.e. commission) use. When I do open up again after this current batch gets done, I'll probably be offering fewer free requests (I'll still do some), though any fee I do end up charging will be fairly small as these things go, maybe $5-$10 tops. If anyone has any experience/advice for making a transition to paid commissions, please speak up (though "charging sux! go to hell!" type comments are *not* appreciated)
TL;DR - Stopping requests on the 15th. When I start up again, I'll probably put restrictions on what I'll do for free and charge a small $5-$10 dollar fee for the rest.
