How do I get my UK degree legalised and certified at the Thai Embassy while in Mauritius?

For those of you who require to have your UK degree legalised and certified at the Thai Embassy, please can you help me with the process? Im currently in Mauritius, Ive been told that I need to have it signed by a solicitor in the UK (certified copies by the British Council of Mauritius will not be accepted), then sent off to the legalisation office in the UK, and then certified by the Thai Embassy (in the UK or Mauritius)? Are there agencies that help with this kind of stuff?
