Mr. Aston is right... this is very common on the t-shirt forum...
People schelp a few designs up on a website and sit back waiting for the brinks truck to pull up with their money.
A website is just a device to facilitate communicating what you do to potential customers. You still have to figure out how to market that website to get it into the hands of those buyers. THEN you have to figure out how to turn that traffic into sales that put money in your pocket.
Otherwise you spend all your folding jack making a website that no one will ever see.
You have to define what the site will do for you. (just an 2-3 page brochure site? ecommerce? SEO tuned? Interactive - forum, blog, comments, etc.)
THEN
You have to define who the audience is for that site. Who is your targeted demographic? Who is it that you want to communicate with?
THEN
You have to develop a site that is effective in communicating your message to your desired demographic.
FINALLY... and the most often ignored...
You have to mave a plan to market the new site and generate traffic to the page. Not just traffic... but QUALIFIED traffic. How are you going to make your buyers aware that your page exists at all?
Without that plan it is likely that your money spent developing a site is wasted anyway. You can spend $25k making the greatest site ever, but if no one sees it then what is the point?
It sounds like you are new and have no site at all now. I'd get a $10/mo shared cpanel web hosting account... then use one of the CMS scripts (Wordpress, Joomla, Coppermine, etc..). If you can't handle that on your own then pay a guy $500 to do it for you while you start working on your REAL site.
You don't REALLY want a website.... what you REALLY WANT is more money in your pocket. For some reasone you believe that your lack of folding jack can be cured by uploading a pile of ones and zeros onto someone elses web server.
That is just one portion of the equation. To increase sales (THIS is what gets you that extra money) you need to increase the number of buyers that are aware of your existance. You need to get them to consume your marketing message (brochure, website, flier, banner ad, door hanger, cold call, yellow pages ad, etc..). Your need to hit them with your message WHEN THEY ARE READY TO BUY. You have to have what they need or want. Your advertising has to be compelling enough to CAUSE THEM TO ACT (buy online with your ecommerce system, call you on the phone (where YOU close the deal), or go find their car keys and come visit your location.
Having a website is not enough... it has to be effective at converting visits into dollars in your pocket.
Having raw traffic is not enough... the traffic has to be from qualified buyers ready & willing to buy TODAY.
Having a good product is not enough. People have to know about it. They have to need it. They have to be able to afford it. You have to be able to deliver it to them as they need it.
