I am looking for a reliable web hosting company to host my site. I am looking for following features:

- 600 MB space
- 20-25GB transfer/month
- Java (Servlets and JSP)
- Perl
- MySQL
- Unix hosting
- Other standard stuff (telnet/ftp etc)

My main concerns are server uptime and support.
Prefer to have some one with 24X7 phone
support. Suggestions would be appreciated.
