Getting a Welsh speaker to help with the 5 minute challenge

Hello everyone,

I have reached the stage where I need to find a Welsh speaker to listen to the five minute Welsh phrases sentences I try to come up with and for them to speak sentences to me based on those phrases.
I would like to know if this is something I am supposed to do with them every day or once a week. Basically I would like to know the time commitment I will be asking them to make on my behalf.

Thank you
