It's a multi-step project. You should probably take some screenshots of your world so people don't think you're giving them a virus. Then you should upload those to an image sharing website. After that, upload your minecraft world to somewhere like dropbox.com. Finally, make a forum post in the right section of the minecraft forums and link the images and dropbox.com URL. I suggest going to the minecraft forums for more help, because that's really all I care to give.
It is not a seed, it is a world download. Look up dropper world download on google or minecraft forums
