Hello there,
Hope you are doing well. We have reviewed the requirement and would like to offer our services.
All the four sources can be worked upon in following way:
Source 1(1027) Records: All the data has to be collected manually as email address are not available on given links and they have to be recorded by visiting the official websites
Source 2(500 records) : Can be accomplished by data manipulation technique, so wont take much time
Source 3(1114 records): Can be automated, however automation will only ensure that what ever data is available the given website is recorded.
Source 4(883 records): Can be automated, however automation will only ensure that what ever data is available the given website is recorded.
We have estimated 40 business hrs to complete this job,and accordingly we have placed our bid.
Please let us know should you have any queries.
Cheers
Ankur
