Ok so I figured this out after looking a bit at the code and the requirements for amqp URI and it should break down into the following format
amqp://username:password@host/virtualhost
My username and virtualhost were the same.
Next up is the nservicebus connection string. I ended up with something similiar to
<add name="NServiceBus/Transport" connectionString="host={host};username={username};password={password};virtualhost={virtualhost}"/>
