Maybe 350 xats and possibly 35 days. No more or no less.
Since you would mainly want someone buying this power from you, you cannot sell it for 150 xats. Make it 120 xats and I am sure you'll get it sold. In day terms, maybe 12 days? That sounds fair to me.
400 xats[selling it at 500 will get you nothing, people can just buy it at the power store for the same price, again you never want to sell a power for more or same[cause u want a profit]
35 - 45 days is fair to me, anything less or more would actually be considered scam to my eyes.
7 days or 70 xats, with 30 xats less you have a good chance to get the xats/days.
1 day or 10 xats, nothing else.
I would never sell days for this one, but 35 days is a good idea with maybe 350 xats the selling cost? I know it seems unfair, but you do want a profit.
All for 15 - 17 days, and maybe 150 xats - 170 xats. That's the best deal your going to get.
Um 8 days or 80 xats? Seems fair to me.
25 days or 250 xats, anything more or less is also scam.
8 days, or 80 xats. Same as subhide and reghide.
I would now sell heart for 3 days, cause its out of sale.
