Need a script for Poshmark website.

Need a script for website which has to be able to do the following:

I need to be able to share my listings from my closet into the feed.
It should not share all the listings serially all the time but rather select random listings from my closet and share them into the feed.
It should share the random listings at random intervals but not longer than an hour and it has to be frequent.

Thanks in advance!!
Will definitely pay.
Please contact me.
