Fair comment however
@Karl1980 , "models" can be a tit-for-tat sort of exchange. commonly known as "time-for" CD or Prints so you'll see TFCD or TFP.
The photographer who needs experience gets a 'free' model, and the mode gets 'free' photos for her time with which to expand their portfolio. Both get something out of this.
In this case the photographer would hire the model, but would pay him/her in images. The model is not so much 'hiring' the photographer
Asking someone to shoot for your direct commercial benefit is unlikely to engender a positive response, particularly if you are looking for a studio shoot (which costs money).
Secondly, you're under selling your brand. I recently recommended that an aspiring male model goes to a professional studio to get some shots, and the results were far better than getting an amateur to do it.
He was representing his brand and using these images to sell himself commercially. Therefore the money was well spent.
Personally, (yes my advice is free

) find a photographer whose style you like, who can deliver what you want. Hire them, get the image and style that you want and then put the expense through your books to make the most of it.
Represent your brand in the best way possible.
