I need someone to design the cover for historical romance ebook.

Information for the business: I write and self-publish fiction.
Design details: I need an ebook cover design which can be uploaded to Amazon, downloaded from my own website and used to publicise the novel on my website and on social media.

The title of the novel is "The Gift of the Nile". It is set in England, in October 1798. The two main characters are a governess and one of Nelson's captains, who has just returned from the Battle of the Nile.

Ideally, I would like the cover to illustrate the moment she first sees him: when she is hiding in the overgrown garden of a semi-derelict Gothic mansion, peering through a tangle of blackberries and yellow roses, and he (in eighteenth century naval uniform) has dismounted from his horse on the carriage drive and is hammering on the door but not being let in. A challenge would be to make the scarab which he wears as a cravat pin prominent enough to provide a visual link with the title. The house is central to the plot, so I would like it to appear on the cover if possible.

There is an alternative scene which could be used, where they are sitting opposite each other at a dinner table (a private celebratory dinner for a dozen plus people), he (still in uniform) has placed her hand on the tablecloth and is describing the Nile Delta to her, tracing its branches along her fingers. They are totally absorbed, and oblivious to the fact that everyone else has stopped talking and is watching them. That would allow a closer view of the scarab. The atmosphere of this scene was inspired by one of the 1970s adverts for Cointreau (links below).

I can supply the text of both scenes, and the whole manuscript, after coming to an agreement, if you wish.
Target audience: Mills and Boon readers
Ideas for the visual style: Watercolour painting or photograph
