Look at it this way.
Everything has costs associated.
Two weeks of war,
this is variable based on the size of the target.
Also variable but you should be able to figure an average after a handful.
this is where you find the issue…
My experience tells me that you want 5-6 high dps battleships to do it in a reasonable time, with 3 logi in case it bites you.
This is expensive.
That said I’ve done it with two Vindis and two logi v guardian’s, myself and a mate dual boxing which is I’m sure much more appealing.
Assuming you and your mate both have an alt that can guardian then your labour cost is fairly low, basically however much it’ll take to get a mate to help.
You will run into the hidden cost of “that timers a pain in the arse” and your mates will be 100% right to ask for more isk do help out.
Then see if that’s under what people are willing to pay for the service.
If it is then good for you but you might find that’s the reason these things are fecking everywhere.
Edit: also, have you a plan for what happens when the tent you’re kicking over happens to belong to someone scary?
