If you go with Blackburn, you have to pay 25 bucks right off, for the web services hosting setup, that's for them to add your account, and allocate resources on their end for you.

After that, for every passing month, you have to pay 5.69 bucks for the service they provide on daily basis.

if you with Randall, they also charge for setup fee, just cheaper, $6 at once, and then for every month is $9.49.

Blackburn for 

1 month     5.69(1) + 25

2 months   5.69(2) + 25

3 months  5.69(3) + 25

x months  5.69(x) + 25, or 5.69x + 25

Randall for 

1 month  9.49(1) + 6

2 months  9.49(2) + 6

3 months  9.49(3) + 6

x months  9.49(x) + 6, or 9.49x + 6

------------------------------------------------------------------------------------

y = 5.69x + 25
y = 9.49x + 6
