Hi Mario. In my opinion, you'd have to spend a lot of money to someone to become # 1 on Google and you have to continue to pay to stay there as the search engine criteria change all the time. I think you'd be better off to spend that money on directly advertising your website. If someone knows your website address, they don't have to find you through a search engine. Spend the money on website content and get a domain name that's easy to remember. If you have areas of specialty, have separate websites for those specialties and they can link to each other. In my opinion, website content is more important than search engine optimazation. It does not do you any good to be # 1 on Google, if your site does not provide the information that someone is looking for. You can have a 1,000 visits a day, nobody will call you if your site is not good.
By the way, I am not saying that your site is not good. I have not seen it. I am just saying that first page placement does not trump content or direct advertising. I personally would also not waste my money on pay-per-click campaigns. It's expensive to and I don't think its cost effective for individuals. Good luck with your Internet marketing.
