i started me own business 3 years ago- landscape design and construction (patios paths driveways garden features etc) was worried sick that id made the wrong move but was confident of my own abilities am now employing four blokes and got enough work for four monthes with the phone ringing constantly- its been a slog at times but i wouldnt change it for the world the only draw back is i just had to write a cheque for the tax man----i hope he enjoys his brand new 749s with enough change for a ducati one piece leathers!!!!
my advice is go for it, be prepared for hard work and best of luck mate
