Earlier quoted context omitted.
for $3k/month i wouldn't expect a competent human being to be on call 24/7, which is what you're asking for. this is one thing that does not enjoy economies of scale. competent people working under pressure at 3AM on a holiday are extremely expensive. would _ you _ do that job? and how much do you get paid?
Rackspace and DosArrest are two companies that currently provide me with competent support 24/7 for products that cost less than $3k/month. They're out there, you just have to look.
