A website design is the one that introduces you to others. Anyone comes to know about you online only on having a website. If you have skills, get your website designed all by yourself. You can always do that, but you must be sure of your knowledge and skills.
Considering some past qualifications will not serve the actual purpose. If you want to have a website meeting the needs of today, you must get updated or get it done by some professional or at least by a web designer who is in the same field, so that he knows the trends.
