The job you describe is exactly what I am currently doing for the magazines Affluent (a Florida Gold Coast regional) and Kentucky Homes & Gardens. I ghost edit the articles for spelling and grammar, check that photos and captions match and write the table of contents and front cover copy.
I have 20+ years experience copywriting about fashion, from budget to couture. My clients include major U.S. department stores, specialty boutiques, websites and wholesalers.
You don't say how many articles each issue has, nor how long they are. So I'm basing my bid on 10-15 articles per issue, less than 1,500 words per article. Please let me know if it will be significantly less or more than this and I will revise my bid.
