I'm not availible for trade at the moment, but I'll tell you where to find a few of them.
1.Bellsprout
Go to New Bark town, and go in the tall grass, by day I believe. Then you should see a Bellsprout eventually. However, I think it's HeartGold only, so if you have SoulSilver and need it contact me and I'll give you a Bellsprout or bellsprout Egg.
2.Oddish
Ilex forest at night. Doesn't appear after you cut down the small tree, though
3.Clefairy
Mt.Moon is bustling with Clefairy at nightime.
4.Pikachu
Yellow Forest route for the Pokewalker has loads of Pikachu. If you didn't get the route during the event, however, you may need to wait until you battle Red at the top of Mt.Silver to see a Pikachu.
5.Diglett
Diglett's Cave, duh.
6.Kakuna
Go to Viridian Forest in Kanto. There's tons of Kakuna there
7.Skiploom/Jumpluff
Near Union cave there's a body of water. Near that water you can catch a Hoppip. When it evolves into Skiploom, use a Rare Candy on it because a Skiploom is a Skiploom for only one level- it will become Jumpluff.
That's all the pokemon I can think of on the spot. Oh, and if you were talking about DPt, just tell me and I'll tell you the locations there.
