Is this going to be 1:1 in scale :wacko ... or just a smaller model? ... in which case the general modeling section is more appropriate to move this topic to : http://www.therpf.com/general-modeling/
The guys are fooling around, don't mind them ... might I suggest using www.photobucket.com to upload your pictures and then use the IMG link to post here ... as for selling you need to get a Premium membership and sell in the appropriate section of the forum : http://www.therpf.com/junkyard/
I for one would love to see your work and recreation of the famous droid scene with Jawa's and Sandcrawler
