I sure do host, I just don't really advertise, its just something I do to offset some of my server and bandwidth costs.

I can work out something around that price mark for sure, $60 CAD
if your site were to use a TON of bandwidth I would need to work out something, but most sites don't, most only use a couple GB a month.
But if it were using say 20GB a month, I would have to charge more than $5 a month, my expense is around $1.5 per GB per month.
