We are finalizing negotiation with our hosting partner (a datacentre in the netherlands) so I can't give any exact numbers yet, but it should be cheaper than KNC hosting ($350 per month per miner). I din't know what you mean with 2 or 3 cents, but one miner is 1KW so it won't run very long on 3 cents 
So, let's say running costs were 300 per month, then:300/30/248 = 4cents/day/share?
Would that be the correct calculation? And apart from this, there are no other fees involved right?
now I see where you got the cents Correct..As for costs; aside from one-time costs to get the stuff working (shipping, tax, power supplies etc) we don't expect any other recurring costs. A complete description of costs can be found in the asset description on Bitfunder (https://bitfunder.com/asset/ADDICTION click profile->description)
