English to Spanish newsletter translation

I'm looking for a freelancer who can help me translate my weekly newsletters from English to Spanish, and also provide proofreading services. The newsletters I'll be sending out can range from topics like health and fitness, travel and lifestyle, and business/executive coaching. Accuracy and knowledge of Spanish language is a must. It would be great if the freelancer has experience in the specific areas covered in the newsletters, such as healthcare, travel, and business. I'm looking forward to hearing from you!
