Edit 4 photos taken on mobile phone

I've taken 4 product photography shots on my iPhone SE. I would like them to be edited so that the garments (which are on a mannequin) do not show the wrinkles as they were not ironed. Also, I would like to know separately what the cost would be if the white background was edited to show only a solid white background.

I have attached one photo as an example.

My timelines are a little tight but based on my former years as a designer I am optimistic that it shouldn't take too long.

Thank you!
