Hola, James. I´m American, a native English speaker with excellent language skills, living in Brazil. I speak a little Spanish, having worked in Colombia, Venezuela, Argentina, Ecuador and Peru (we speak Portuguese in Brazil, which is similar to Spanish in many ways - I am very fluent in Portuguese). I used to write, translate, proofread and edit reports, correspondence and technical manuals for multinational corporations in the oil business. Now I perform similar services for book publishers and authors, and university students who want to publish their academic work in perfect English, as well as blogs, sites, courses, etc. I looked at the texts you sent here, and will have no problem correcting your English. I am not familiar with gambling, aside from some experience with horses and poker, so I may need explanations about some points in order to make them clear to your readers. I would like more information about how often you might need my services. Also, I prefer to work for fixed rates (for example, edit 5000 words for $100 USD) instead of hourly rates, because sometimes it´s difficult to prove how much work you did in an hour, which can lead to unpleasant conflicts. Please contact me with more details. (PS - have you ever thought about offering a course in betting?)
