Sws powerlvling - L2walker

Hi, I've got a little problem. I'd like to powerlvl my little char with Sws (both boting). I'd like it to be like that -
1. Char1 Fights, Sws Follows
2. When songs are over, sws invites Char1 to party, sing, and leave the party.
3. <same as 1>

How can I do this?

buy a nostromo or use a key presser to invite him every 2min and in the 0,5 he will song after this u need a key presser to press dismiss of the party (so i did it worked fine where i did use it)
be sure nostromo/G15 is best way!
