I don't know of any website, but generally speaking what you need to do is join the mailing list for your main disciplinary organisation in the UK (I'm pretty sure you are in the UK). This organisation will have an annual conference, and maybe a postgrad one too (which can be a nice way to start out) and depending on field, there may be expectations that you present there at some point. Through the mailing list, you will get sent adverts for smaller conferences and workshops. I doubt you'd get a full conference on your method, more likely there might be a specialist workshop. This is the safest way of regulating for quality as they will screen for the dodgy stuff. Basically conference adverts arriving in your in-box as unsolicited mail with titles like the international conference on the humanities and social sciences are the dodgy ones.
