How about 15 % the first six months and the second six months at 12 % with a guarantee of 3000 units ?   That's a lot to sell with very low profit margins .   It's about the best we can do , Smith . We need to hammer something out today . If I go back empty-handed , I may be coming back to you soon to ask for a job .   OK . 17 % the first six months , 14 % for the second .   Good . Let's iron out the remaining details . When do you want to take delivery ?   We'd like you to execute the first order by the 31 st .   Let me run through this again , the first shipment for 1500 units to be delivered in 27 days by the 31 st .   Right . We couldn't handle much larger shipments .   Fine . But I'd prefer the first shipment to be 1000 units , the next 2000 . The 31 st is quite soon , I can't guarantee 1500 .
