That is where you sign. Makes it all legal. Mail it in...You will need the HIC number if you do hardscaping or drainage that totals over $5000 per year. Good to have, you wont need to worry about having one if you do a job requiring a HIC....Unfortunately, no state license for hardscaping. Grab a paver or wall unit and throw it down! LOL....Seriously, you should go to a few hardscaping seminars before doing any. Hardscaping is not rocket science, but EVERY step is important.....On the ficticious name, if you use anything other than your sir name, it needs to be registered.
