Proof reading of IT and business texts

Need some proof reading with careful and sensible edits from time to time of marketing texts for IT and business themes. We need a native Brazilian or Portuguese speaker for this having an experience of copy writing and spell checking on information technologies and knowing such terms as server, ERP, CRM, BI, information security. etc... This is not just a spell checking but a reasoned approach to make the texts sound good!

If you are interested please send your text portfolio and your prices for copywriting and proof reading.
