Looking for a special job system or holding settings /w daily limits

hello

i'm currently settup up a little bukkit server (v1.7.2) for me and a few friends.. nearly everything works fine but i'm looking for a job system that works other than all i found on bukkit plugin list :/

all job plugins i found works with collecting/farming items and get money for each instantly. i'm looking for a plugin that's works with selling items to the server.

so, yes, an adminshop should work for me, right? but i want to limit the daily earnings, so that the economy on the server is controlled. for example users can sell items for x money per day.

du u know something like that? i looked for job systems and holding systems. currently i use iconomy, but i think there's no way to limit the max money for getting money from the server. and getting money from other players should't be limited :/

i hope u can help me

greetings, pete
