My website cost me £400.00 it's not bought me in any work, but its an easy place to direct clients to, so that they can contact me and see my details.
If you work hard enough at it, I hear website can bring in loads of work. I'm established and don't need anymore work, most of mine comes from recomendations and regular clients.
Do a good job for people, leave a few cards, and always turn up when you say you will, and do quality work, and your business will grow.
I'm updating my website next month, it'll cost me another £100, but I feel its money well spent to have a proffesional site, and image. I wouldn't dream of having a go at building one. What a pilaver! Writing on this forum and playing Xbox is as high tech as I get!
