Made an amazon site - looking for help

First of all I apologize if i'm posting this in the wrong section but this is my first post!
Ok so i recently started searching through BlackHatWorld and reading peoples success stories.
I saw allot of posts about people doing very well with amazon sites.
SO! I decided to go all in! I purchased a domain and hosting for a year and started coding my website
I only know some basic html/css so my site is simple.

I've been advertising it through craigslist only because i'm not really familiar with anything else.

Example add--------------------------------------------
Tittle:NEED TO SELL! IPHONE 5! MUST GO!

Cost: 125

[Picture of someone holding an iphone]

Body:
I bought it a few days ago but now I need the money! Please email me ASAP! IT WILL NOT LAST LONG!
----------------------------------------------------------

And this worked! I also posted one about an ipad and a few about computers.
I woke up the first day with over 100 emails!
I emailed everyone back with this:

"Hey sorry it sold! But I bought mine for cheap! It was great deal and i got the link for you: MySiteUrl"

This method seams to be working a bit.
I say "a bit" because i'm getting the traffic but no conversions.

SO! BlackHatWorld i come to you today asking for advice!
What can i do to improve?
What Tuts should i look at?
Please tell me anything you think i should know!

you're bringing in traffic that's looking to buy an iphone for $125, no wonder they're not converting.
try placing ads for accessories, like earpods, cases, cable etc with a real price or something close to it and then bring them to your website. if someone is looking to buy an iphone for $125 and he goes to the website where this is $500, he's not gonna buy. but if he's looking for some headphones and found your ad for $10 and goes on the website and they're $12, maybe they'll buy. anyway there are higher chances.
the point is to bring quality traffic. you can use this traffic to send it to a certain page where you have a content lock. grab their e-mail and send them some offers later. higher chances of converting.
