cloud bitcoin mining backend software?

[audricd]

Hello. I am thinking of setting up my own cloud mining company.
I would like to know if there is a software for managing such business. Like there is PTC Evolution for Paid To Click websites, OSCommerce for webstores.. and so on.
I would like a system that of course manages sign ups, contracts and automatic payouts.
I am a webmaster and I know my way around PHP MySQL and such but I wouldnt be able, no way, to code the whole system by myself.
Thank you.
