I think it's a good start for new photogs who really wants to get into architecture photography. Understand that pros here see this like a peanut pay but for those who wants to get into this specific line of business they may see it as an opportunity.
NO!
In fact it is a very bad start!
A good start is where you enter doing things the proper way of sending a quotation, discussing client requirement, reckee and research, requotation if need be, discuss rights and liabilites, and contingency plans, then confirming the assignment by way of contract, fulfilling the work, delivery, invoicing, getting paid. Thats where you learn.
Taking up this offer even a pro will be shooting crap pictures simply because of the lack of understanding in regards to time, weather and coordination.
Good photos doesnt always happen point and shoot. It takes concept, timing, preparation.
Might as well go shoot your own leisure stuff. No need to answer to anyone. If $80 can buy you for 3 days, nothing I can say.
You go rent a camera plus a lens already $100 for first day. So TS is efficient renting your full set of gear plus your labor, time and post processing work. Calculator very good.
