I agree with Kyle as well. Take one topic at the time, say green leaf wall art that Kyle suggested :).

Write a blog post about green leaf wall art. This can be a review site, "10 coolest green leaf wall art" and then you link each product to their merchant site.

Let us know if you need more help,

What Kyle said is spot on. There comes a time when you feel overwhelmed with the amount of things that need to be done. Break the huge tasks down into little parts. Take a look at the WAbinars. Jay did two series on getting started.
Here are a few that will help.

Just keep at it. you have a good concept and there have been some good advice in the comments here. Best wishes and God Bless.

Maybe you could look at niches like Lighted Leather Kindle Covers/cases - This type of case/cover comes in an array of colours and you could write on the Green Lighted Leather Kindle Cases... Just a thought.:)

Hey Chelc good job getting your website up, hope you get the help you need soon you are in the write place.

thanks Kyle never thought of those angles

Also, a lot of people are searching for different types of green items. Lime green, mint green, neon green, etc. You can tackle all of these pockets of keyword as well. I have a good technique that I use for uncovering an unbelievable amount of keywords:

http://www.jaaxy.com/blog/alphabet-soup-the-most-comprehensive-keyword-research-technique/

Make a list of 10 green items and then write about them. Do a bit of keyword research on them. Here are some things that I quickly came up with:

-green leaf wall art (under 20 competition)
-lime green abstract art (under 100 competition)
-green furniture (67 competition)
-green painted furniture (19 competition)
-green bedroom furniture (51 competition)
-blue green baby bedding (91 competition)

The one thing that you need to be careful about is that green is also used for "eco friendly" so don't confuse a lot of the keywords for these instead of the color.

People that succeed online or offline push harder when they get discouraged. Those that fail give up...just remember that. This is your tipping point and if you can overcome times like this that seem a bit overwhelming, you will be able to achieve any level of success that you want. :)

You can write about difficulties about find a green case, you can also write about iphone cases in general. go to google alerts, make an alerts for "green ipone case" "iphone cases" and yes use quotes, this way articles about cases posted on the net will be sent to your email. Join some forums, search iphone case + forum. Learn why people want green cases, only because it's their favorite color? Maybe. Learn why people want things, people want things for different reasons. Find these different reasons and make write articles about these reasons. Find information in forums and even articles related to your product, read the article and comments left in the article, read what people are saying and why they want something, dig deep into their brains even if that don't come straight out and say it in their comments

If you're going to be selling A lot of things your will need A lot of content . Its ok, I do the same thing.
