Content creators needed - English as a second language for Spanish speakers

We are looking for expert content creators to help create e-learning content for English and a second language for Spanish speakers. Please bid ONLY if you have past experience in creating ESL content for Spanish speakers and have taught English professionally to Spanish speakers. We will not allow any copyright infringement so please bid if you can help create content from scratch (referring sources for structure etc. is fine). Do not bid if you plan to copy content from websites/ e-books. We need quality content which is conversational, builds a strong grammar base and is intuitive. This is needed for 10 hours worth of lessons for basic level (beginners)
