Stock Images - Multiple Requirements

I am a photographer based around the Leicestershire area and I am looking for models who are available to take part in a stock image shoot. All ages are welcome to apply as I have a few different ideas. I am hoping to do some fashion stock images too so will need standard runway models with experience. Also looking for child and teenage models who will need to accompanied by a parent or guardian. Payment will vary from job to job as some people will be needed for longer.
