Writing and Publishing: Paying for a Book Cover on Fiverr

Well, I’ve been doing some more research, and now I am going to try to pay for someone to design a cover. So, I got on Fiverr (a website of freelance who offer their services) and paid $11  to have a cover designed for my first book (The Recruit). 
Now, after I paid, I got a weird Q/A page. First of all, it asked my the industry my book is about. Well, the categories didn’t include fiction. So much for that.
Then I got asked the title, subtitle, author and size/# of pages in case of print. 
And then, it asked me for a photo.
Why would I pay for someone to design my cover if I have to provide the photo? I know how to use photoshop, my problem is not using a design program, my problem is choosing the right photo.
So, I wrote what my book was about and what kind of photo was recommended.
I there I was thinking I had paid to be forced to find a picture, which basically meant I would loose $11.
A few hours later, I get an email from the designer saying she is working on the cover.

After 3 tries, I finally decided on a book cover. 
Here it is!
