700 contacts called ASAP - £50 per 100 calls

We have just under 700 contacts that require calling ASAP.

All of the contact names and phone numbers have been put onto an excel spreadsheet and have been contacted via email with an introduction and now requires 1 or 2 people to follow up the email to see if it is of interest and add the notes to the excel spreadsheet.

We are looking to pay a fixed price of £50 per 100 calls made.

There is a bonus in place of £10 per contact that either signs up to the new product or £5 per contact that requests a call back with further info.

I need this done ASAP, so please submit your best possible price, indicating if it is for 100 or 700 calls achieved and when this can be completed by.
