The cheapest dedicated hosting plan with GoDaddy is $99 per month.
It goes up pretty dramatically from there.
I know that shared hosting is cheaper, and can be fundamentally almost zero "down time", depending on the hosting company.
Again, from GoDaddy, shared hosting can be a little as $5 per month.
(not appropriate for this site)
But, a better package offers unlimited bandwidth and storage, and costs $6 per month.
And they guarantee up time of 99.9%.
Ask me how I know ????
