I had a very quick look at your web site, I am not a Techie, to my eye this seems like your design work is a generation behind current, an older model if you will.
Now if you are working with ultra conservative business’ that want a retro look great, this will appeal nicely.
However your website is your primary marketing piece, what you do for yourself is an indicator of what you will do for me.
In art school they teach painting by making you learn to reproduce the masters stroke by stroke.
A great tip I heard on a Canadian marketing podcast (the “effective edge” from memory but I’m not too sure about that) was that the high profile consumer micro sites for cars and electronics are the undisputed masters of web design trends.
Their reasoning was that these sites roll out with each new model and are never left to stagnate.
Big businesses will have big budgets to get their sites "just right" to give the exact modern look they are after.
They set the trends in what’s new in website design in much the same way as the fashion magazines work in setting clothing trends.
What I am thinking is that if you learn from and apply what is new at these sites you will always be in the “Current Style” when you are developing your own and customer sites.
Apply this approach to web design and presto you now are filling a Niche of “Big Company looks on a small company budget”.
After all “Mr site” can do the low budget site in a box look better than the rest of us and still get the customer to do all the work themselves to boot.
PS: if you are short of Portfolio clients make some up (no not like that), buy some cheap domain names like Savethedolphinsofthenorthwest.org and code them as social responsibility sites.
This will show off your latest design concepts and after all, will the client really complain about it?
To maintain ethical standards your links for those seeking to donate, request further information and contacts would then be a click through to local charities, government contacts and support groups.
You may even get to quote costs as tax deductible while highlighting important social issues.
Not to mention the Kudos with your clients for your charity work.
