I have to learn threading-help!

[Cridelbuono]

Hi everybody! I did a bit of market research in my area to see what treatments are in high demand and apparently there's a huge gap in threading field: only one place offers it! And they have only one person that does it, so it's pretty much impossible to get appointments and a lot of people require it and go way out of their way to get their eyebrows threaded!
Can anyone suggest a good training course? I'm based in Oxfordshire but I don't mind to travel to get a good training.
Thanks in advance!
