Debian Linux server rental for 3 months

A development project i am working on requires i do some development and testing to get my application working on a Linux server. I need 90 days of rental on an existing XenApp server. Obviously i will need the ability to install my programs on that server and then run them remotely to ensure that my code is working properly. I am in the UK and will provide any credentialing needed to confirm my identity. This should be easy money for someone with an existing server that they can spare. I need dedicated use of the server and an unrestricted internet connection at or above 100mbps (we need to be able to download at around that speed). Servers with more CPUs will be favoured (16 or more cores would be good).
