Hosting For Corporate Site (low Traffic, Uptime Important)

i work for a small but fairly successful and quickly rising company. we're looking for hosting for our corporate site. we could host it ourselves but that would put an extra burden on engineering and we're stretched pretty thin as it is. we moved to bluehost on my recommendation. i've been using them for 2 years now and never had a problem. unfortunately less than two days after we switched the server is now down. it's been down for over 4 hours now and we've blown past several estimated times from tech support. i know this is a rare thing but it doesn't look good and i don't think the higher ups much want to stay with them. so here's some info about our site. requires SSI, CGI, Perl 5.8+ with Perl DBI 1.32+ and Perl DBD::Mysql > 2.1021+ Perl Modules, ImageMagick 6.0.6+ Perl Module or GD Perl Module (GD.pm 2.17+), PHP 5. small traffic with occasional spikes. approx 200 uniques daily. occasional spikes if we happen to show up in the news. we do have the possibility of showing up in all major US news outlets. it's happened once before which resulted in almost 1,000 uniques which quickly tapered back off to normal levels. we're currently using 154MB of disk space and 8GB of bandwidth last month. we need multiple ftp accounts to allow marketing and contract web devs to upload their own files. probably around 10 or so would be adequate. email not required. we have a hosted exchange server. uptime and quick response to server outages important. being a corporate site and not our application downtime isn't truly horrible but it is perceived as such. this site is our identity. we're a tech company and it looks bad when our corporate site is down. even when our application isn't.
