I know you say you don't want to consign yourself. JBF does have a service where they do the tagging for you. I know the Fort Worth one does that, I'm not sure about Arlington or North Richland Hills.
I wouldn't recommend Kid-to Kid. I've been to Divine Consign and I believe it is just JBF. Most consignment stores don't give you much for the clothes, be prepared. They have overhead, employees, light bills,etc..., so they won't give you as much do to their overhead.
I think E bay might be neat to try. I know there are some services where you take your things to EZ Bay and they put it online for you. I'm not sure how it works, you might want to check into it. You could also put an ad in the paper, however you would have to put some kind of price on it and talk to the buyer.
I shop JBF and found it is the best route. Divine Consign is good place to try also. The smaller shops won't give you as much and don't have as much selection as JBF/Divign Consign.
