just post something like
"ISO (in search of)..." whatever you are looking to try, and im sure people will come and help, but since you are new without cred, you'll have to send first, which is standard.
or you can try a "blind 5er" trade to see if you get any bites.
in fact, im sure if you said you wanted to trade some gurkhas Thunder.Gerbil would come along and trade with you.
