Site buyback

I would like to do a site where the client sells his phone. To do this, a friend advised me HikaShop.
So could tell me please how to set up the site.
I would like the client selected state of the phone.
Then a price is displayed depending on the state..
Ex: Good = 30 €
       Poor = 15 €.
Then after selecting the phone status, if the client is okay he clicks on sale.
And if it is connected, it receive an email confirmation show the procedure to follow.
Or if he has not account, it was asked to register and provide their address.

Hi,

You will have to create characteristics: www.hikashop.com/support/documentation/i...html#characteristics
Then create a product, add the characteristic to the product, click on "Manage vairants" and set a price for the different variants (the state of the phone in your case).

Then it's a common checkout which will be applied, you will just have to edit the mail content to explain the procedure, the emails can be edited via the menu "System > Emails" (business edition).

Thank you for your answer, I'll try that

I tried to install Hikashop on my site, but it does not work. here is the answer of the browser (Chrome) :
ERR_EMPTY_RESPONSE

Hi,
Can you tell me how many characteristic (with their number of values) did you set to your products ?

I have yet to put anything because joomla refuses to install HikaShop! I do not understand why it does not work.
Is there a other way to force joomla to install HikaShop?

I tried with ftp and when I run it it gives me this error

500 - An error has occurred.
View not found [name, type, prefix]: menu, html, menuView

Return to Control Panel

It's good it works.
Now back to my first problem.

I would like to create a list of phone.

When the customer has selected his phone he wants to sell. It clicked.

Before the price appears there are four states of the phone he should choose.

1: new
2nd: good
3rd: Poor
4th: does not work

And in the condition that he chose the price changes.

I would like to insert the image of each phone.

So when he chose the phone and its condition, I would tell him the steps to follow for buy back.
As saying:
Now that you have selected has this phone please put it in an envelope and sent it us, after inspection we will send you your check.
