✔ 最佳答案
I live in Canada, and we usually just use very simple English, so I would translate this sentence as below:
"We would like to invite you (or your company) to come to our office to perform a training session, details as follow:"
we usually don't say "we sincerely", but you can always put "Sincerely Yours" at the end of the letter, before your signature.
Hope this helps.
