Need Spanish Language Expert to Add Pronunciation Guide to Phrasebook

Hello! We are a language-learning publishing company expanding into several languages and have already written several books in Spanish. One of these is a Phrasebook, which has been created to help beginners become familiar with basic phrases such as ordering a meal, asking for the time, apologizing and calling for an ambulance, among other things. The book is finished, but it requires a freelancer with experience in the Spanish language (native-level only, please) to add the pronunciations for each and every phrase used in the book. Candidates will also be required to speak fluent English, as you will need to make the Spanish pronunciation easy for English speakers. There are over 1,500 phrases, so there will be plenty of work. We are paying $2.00 for every 100 words, and each phrase contains several words to create pronunciation guides for. We shall provide you an example of what we're looking for. If you have read this post and wish to submit a proposal, please start your cover letter with the Spanish translation for "rainbow". Failure to do this will lead to a rejected proposal. Thanks for your attention! Good luck.
