Homer said:I suck at graphic design so it is really hard for me to try and make these myself. I may be able to just modify one of the core skins to meet my needs though by just changing some colors.
Why not buy a phpNuke skin, or Mambo skin, or some other skin and modify it to work with dotnetnuke? Its easy really... most skinning engines just require tags to be inserted where the content lives... so if you buy a mambo skin, you just need to change the tags from mambo to dnn tags... with maybe a little tweaking. really its just the design you're buying.
