I think I'm being scammed

[Greyfish]

I recently put a domain I own up for sale and a couple days later I received the following e-mail.

Hello,
Your domain name has been found online.
Please let us know your price.
We make money on selling and buying names and sites. Now the domain business is very attractive.
Looking forward to do business with you.

Regards,
Anthony Ogilvie
General Manager
EI LLC

So then I replied to the e-mail with my asking price, and this is the response I received.

1000. Ok.
Do you sell domain with a web site or just the name?
Domain without content is ok with me. Web site is not necessary.
Have you had your domain names evaluated in the past? I mean domain appraisals. Without valuation we cannot be sure in the sale price. It's very important for me in terms of reselling too. But we must engage a valuation company with REAL manual service. So I will only accept valuations from independent sources I and my partners trust.
To avoid mistakes I asked domain experts about reputable appraisal companies.

Please check this blog with suggestions from other sellers and buyers:

If, for example, the valuation comes higher you can adjust your asking price accordingly. It will be fair. I also hope you can give me 12% - 15% discount.
After you send me the valuation via email (usually it takes 1-2 days to obtain it) we'll continue our negotiations.
What is your preferred payment method: Escrow.com, International wire transfer, PayPal.com or something else?
Hope we can come to an agreement fast.

So I checked out the blog link that he gave me (look at it for yourself), and I feel that the site is fake and simply a marketing scheme for easynamesale.com, here are my reasons.

1. I've never heard of this blog
2. This "domain blog" is hosted on by 007sites.com, a free hosting service
3. The page claims to be "Powered by vBulletin" but the structure and mark-up of the page are not consistent with vBulletin thread archives
4. Every post in the forum seems to favor easynamesale.com for domain appraisals
5. The root of the blog link (http://domainblog.007sites.com) is nothing, if this blog or forum is real then wheres the actual site?

I feel like I am simply being scammed into purchasing a domain appraisal from easynamesale.com, and once they get my money this "supposed buyer" will simply back out.

Eliteinvestment.net (the e-mail address the buyer contacted me from) and easynamesale.com have surprisingly identical HTML markup and structure. It appears as though my "supposed buyer" owns both of these websites. What do you think?
