Every website needs HTML+CSS so the market is huge! I am a full-time freelance html/css developer and make thousands a month with NO advertising (all I have is my good looks and charm ) - that gives you an idea of the potential if you actually do advertise! I've always sucked at the whole marketing side of things which is why I've stayed out of it.

These sites can run on autopilot for the new owner - you just get the work (easily gotten from forums, SEO, adwords, design firms) and I can get it taken care of, leaving you a nice margin (~$100 a job, so if you get work for $150 then you make $50/sale). If you are a developer, then you can do the work yourself and get 100% of the revenue as profit.

These sites are unlaunched and therefore don't have any traffic/revenue.

WPNinjas - www.wpninjas.com
Bought the domain, paid l3fty to do the awesome ninja character.

StandXHTML - www.standxhtml.com
Domain and design were purchased for $150. I coded the rest of the site.

Revcoders - www.revcoders.com
Bought this from the old owner for $250. Paid a designer $100 for the design, which I then coded.

Total Costs
WPNinjas: $10 domain + $40 character (I designed+coded the site)
StandXHTML: $150 domain and design (I coded the site)
Revcoders: $250 site and $100 design (I coded the site)
Order Form for all 3: $200 ($66/each site)
-------------------------
$750 - not including the many hours I personally put into it.
-------------------------

I am going to sell them individually, as not many people I imagine will want all 3 (and if they do, they can simply bid on all 3)

WP Ninjas
BIN: $250
Starting Bid: $50

StandXHTML
BIN: $250
Starting Bid: $50

Revcoders
BIN: $250
Starting Bid: $50

Minimum bidding increments of $10.

Why I'm selling - I already have my personal portfolio www.matthewrochow.com and don't really need them. I made these to market them via adwords mainly.

Any questions let me know
