Can you correct it please?
A MNelson Consultores e Investidores Associados, performs in the national and international market for nine years and stands out in the consulting and
Business executive area thanks to it’s high quality level in attending it’s clients
Thank you again
I'd change this a bit:
A MNelson Consultores e Investidores Associados, performs- there shouldn't be a comma, the verb should be in the present perfect and 'performs' doesn't sound very natural to me-
stands out in the Consulting and Business Executive areas (or no capital letters, but be consistent)
thanks to the high quality of service provided for its clients
