Cut out images of clothes

We are looking for cut out images of our range of maternity fitness wear. We have lifestyle images of the products but need shots with no models in them.

If it is possible to edit the images we already have to cut the models out I can provide high res images to do so. I have attached an example of the type of picture we have. if this is not possible please let me know what the options are. The full range of clothes can be seen here: www.fittamamma.com

I look forward to hearing from you.

Thanks
Alex
