A portfolio is a must - folk will need to see the kinds of images you can produce & your creativity in showing off products, whether they be jewellery, clothing, plastic tubs or curtains

Something which might be worth considering is a collaboration?
You produce the image(s) & retain copyright on it, giving the model/manufacturer/hairdresser etc permission to use the images for promotion of their own services, giving full credit to all involved parties, but no rights to sell the image(s).
Depending on how you arrange this, speaking from a product manufacturer's viewpoint, I would either send you some accessories to keep or to give to your model in "payment" for his/her time or you might very kindly offer to send them back to me. I would expect to pay for the postage both ways, as I would be receiving professional images in return for use of my accessories. I know that I'll also be getting some cross-promotion through everyone involved e.g. the model will post photos to her online bases, as will you and the make-up artist.
It's a great way to start out and will help you build your portfolio. You will also be helping other small enterprises build their own brands/image.
Of course, it involves you spending some time & money, so don't go overboard & do too many collaborations or you'll soon be an ex photographer! lol But it's definitely worth considering IMO.
