Suitability for this Job
1) I have travelled a lot in various states of India. So quite familiar with lots many places.
2) I plan my vacation, so I know about nearby airports, train stations and buses.
3) You can provide timeline for completion of work. But I think it is very large data base so lets go State wise.
Doubts in my mind
1) Per hour work is now done on freelancer desktop app. So are going to do use that??
2) They generate invoice based on rate per hour/weekly and not on SPOTS like you have mentioned in your description. Please clarify.
3) You need Name and address of airports( or nearest airport if airport not available), train stations and inter state Bus stations in a Text/Notepad file. Now this is extra than just marking the spots. So will you pay extra or it will be counted in per hour rate?
4) Please create a milestone.
Charges
1) if i have to work on Freelancer desktop app then i will charge Rs 125/ Hr and will spot 10 places every hour.
2) if not on that than like you mentioned 3 hour billing for 30 spot and 6 hour for 60 spots, where also Rs. 125/hr.
3) Making a notepad file will cost extra but same as above. e.g. marking 10 airports/train/bus will be charged as 1 hr work.
