Each one has name of contact, company name & address and email address.
For each entry I need the email address verified that it is a current valid email.
In addition, I also want the LinkedIn profile for that contact provided.
Lastly, if there is a direct phone no. for that contact then that should be provided as well.

1) That you will be able to complete the job within 10 working days from the date of receiving the data

3) Please tell me briefly HOW you are going to do the Job - i.e. what steps, methods, systems you will use.
4) You need to have done a similar job before and need to have reviews on you page to prove it
LASTLY, when you put your proposal in please ensure that you only request up to 40% of the total fee as a deposit (i.e. £60). I will NOT pay more than that as the deposit
