Hey all, I have a large (for me) project 8k, 20 tons of stone and 1000w of light ect. I need to go collect my deposit in the next few days. What type of contract do I use? I have contracts on all of my maint accounts but none for installs. I dont want her to change her mind after I order everything. She sounds cool and is a maint cust, but I have had people show their bad side when you least expect it. Any ideas?
