[Serusers] fee-for-service SER server

Dear Wizards, Many of you seem to be running public SER servers with hundreds of users. I would like to become a paying customer of such a SER server, but cannot find any such services advertised on the internet. Can someone please recommend a running, fee-for-service SER server? A few weeks ago, I asked this same question, and got zero responses. And I mean no responses of any kind. Is this the wrong forum to ask such a question? Even messages pointing out why I am a total idiot would have been preferable to total silence. If there are reasons that it is not practical for anyone to operate a fee-for-service SER server, I would love to see some discussion of what makes it so impractical. Please feel free to speculate on why you think such services have not been created. thanks, Michael
