Hi,
I've bid on this project pretty low since I've just begun on Freelancer. I'm a Data Analytics professional having a very good understanding of Excel Tools and Mind training to deal with garbage data.
In this project I assume, that:
1. There're only one word first names, and one word Last name of users. I.e. Max 2 words per name
2. You need 19 different permutations for each mail id as per predefined rules.
3. There's no other data dependency.
If these are true, I would just need a few hours to complete the task and hence I've kept additional time buffer to ensure no garbage data is there. I also assure you moneyback in case you're not sarisfied.
Regards,
Rakesh Sehgal
