Online book cover

Hi,

I need a quick book cover for my fun story on Wattpad to help me promote the story and look a little more professional in my outlook.

The story is here: https://www.wattpad.com/story/152322805-a-very-english-necromancer

All I am after is a quick cover for the work to replace the crap that I've put there! - Please do totally ignore the thing I chucked up, that was just so I had something but by no way should affect a real design!

I'm just looking for someone who can bang something quick but good out in half an hour or so - I know you guys are out there! This is just a small personal project, so I'm not really looking to break the bank.

If you think you can do something in budget which fits the story and will entice others to read it, please let me know and show me your portfolio - oh, and do read a bit of the story first to get an idea, it's only short so won't take any real time.

Size for the cover is listed as 512 x 800. [edited to update correct size requirement]

Thanks
