Just arrived in Alicante (Valencia)

Hola everyone! As mentioned I arrived recently in Alicante via Denia (mint town). We are involved in developing young student/footballers from abroad here in Alicante together with a pro club, I am based in San Vicente del Raspeig. At the moment we are looking for any tips on legal requirements for businesses here, please chip in graciously. In addition I'm in need of a business accountant who knows the local legal aspects of business to be executed here by a UK based company. Also looking to purchase a car for up to Protected content , plus a mini-bus that can seat 12.
As I say...glad to be here & enjoy your company!
