hey backend/data processing developer here
i've done a gps app with offline map. i have work samples to show if you would contact me. the app was for the purpose of not canvassing on the same location twice and so movement line were shown on the offline map. i think i would also be comfortable doing route optimization for you
you mention you have a "unique new business process", do you have one or do you need it developed for your expanding buisness. or in other words your going fresh start
#1 is ok
#2,3,4 is like after you have the route planned out, you put the first delivery package closest to the driver and the last delivery package furthest from driver. the driver can scan package to verify they delivered it someone's home i'm assuming and also they have a mobile app map showing them where to drive
#5 live tracking of the delivery van.
#6 customer calls van driver/call center to let them know they're not home at a certain time, please arrive at another time when i'm home?
i think for all this, i think $750 as a budget is low, but if that's just your price for interviewing people and consulting. doesn't hurt to overplan. i like that big consultation price. good planning saves you a lot in costs, totally worth it.
please contact me
and i'm fine with nda, you owning the product. i work on downpayment, completion pay. my downpayment is pratically the consultation fee, so how big is your total price then, 7500, 5000, etc?
