Unpretentious online store

You need to set up an online platform for purchasing so-called "shoutouts" (promotional posts) in Instagram.
The functionality of the site should be like ), with reservations:

1. It should not look like this misery.
Want site meet people from the Internet.
To entering it, didn't want to rip our eyes, as in this case.
2. Website design should be in dark colors. More white, black. Without bright colors, but color may be present.
3. Payment: PayPal
4. At the moment the posts are sold only in one account. As time passes will be sold in the posts 2-3 pages.
In the admin panel should be able to easily add new accounts, options for the purchase of posts and so on; without the twisting design, and anything to each other did not interfere.
In General, it is important that everything looked beautiful and harmonious.
5. After successful purchase via email should come the details (the photo is what was specified upon purchase)
6. If possible, each purchase must be made in the excel file. Ideally in Google Docs.
7. Responsive design compulsory

Payment: PayPal. Thus, there is a money back guarantee when cheating.
For me critical invoice. Can't provide – no contact.
