Opening business in Europe while living in USA

I am Spanish and plan to open a business in Europe to export to the US from different European companies. I live in the US and don't want to move to Europe yet. What are the implications, taxes, etc...? What is the best way to do this business? <BR>Do you know of a website that I can go for reference?<BR>I would like to know if there are any implications because I am still living in the US. Will I be taxed in Europe and in the US?<BR>Also, I will be traveling to Europe but will not need an office there. Do I need to have a valid address in Spain? Do I need to open an office and have someone local work in it?<BR>I would really appreciate if you can give me the information or refer me to the correct source.<BR>Thanks in advance for your assistance. <br>Flor Ollarves<br>
