Marketing for skin care product

I'm looking for a marketing specialist to help promote a skin care product specifically designed for women. The focus should be on social media, reaching a wide variety of people with our message. Our budget for this project is under $500, so we're looking for ideas on how to get the most out of our limited resources. We will need the right person to create a plan for us that maximizes our reach and drives sales. If you have experience in marketing with a female focus on social media, please let me know. This could be an ongoing job for the right fit.
