I agree with the other responses recommending that you might as well create the site yourself if cost is a serious concern. I feel that a cheap designer will often give you exactly what you pay for – a cheap looking website.
If you do end up making it on your own I encourage you to consider the following questions before deciding what service you’ll use for creating the site:
What are your goals for the site?
-Will it be used to only advertise your services or will you use it for more than that?
-Do you plan to provide content through it like blog posts, white papers, links to articles, product reviews, etc.?
How “tech savvy” do you consider yourself to be?
-Do you want to simply “fill in the boxes” of a template that limits your design options or do you want to have more control over that?
-Do you know or are you willing to learn simple CSS and/or HTML5 code to have more control of the overall look/design and feel of your site?
There’s plenty more to consider beyond these questions but they should hopefully get you started with thinking deeper on the subject.
Another idea would be to see if you could find a local web designer who would be willing to “trade services” with you (AKA you provide them personal training in exchange for the work they do on your website). Would this be a viable option for you?
Let me know if you need me to clarify anything above. Best of luck to you making the most out of your eventual website either way!
