" but regardless im not interested in the issue of chargebacks I just want to know if theres anything available for letting people sell BTC's."

Same reason there isn't a wordpress plugin which allows you to randomly corrupt files on your webserver.   Not being interested in the issue of chargebacks is horribly naive.  Bitcoins can never be reversed.  It is pathetically easy to reverse a digital transaction.  Take however easy you think it is and it really is 100x easier.   A brain dead chip could steal from you day in and day out with a plugin like you are asking.

If you want to accept reversible funds for irreversible funds then you should do the heavy lifting yourself and hopefully in the process realize how horribly risky and likely unprofitable it will be.   It seems you want an "easy button" which would merely be an easy button for losing money.
