You have to setup Bulk SMS Software with SMPP Server for me, with reseller panel, client panel and admin panel. If you have previous work experience in this domain, then only apply.
I have one SMS management software readily available as I have got one developed for an old client.
It has all the above mentioned features. Message me if interested.
