Automated collection of business data with email

Description

We are an email agency and are looking for a reliable and experienced data collector who can collect data from Google Maps based on industry and country. You are expected to research sub-industries provided (for example manufacturing > steel manufacturing, automotive manufacturing, technology manufacturing etc.) for which you may use alternative directories, however it is vital that all data is gathered from Google Maps only. All contacts must have a verified email (we can not accept contacts without email or with emails which have not been verified = this means you will probably have to collect 2/3 the total amount as you will lose non-suitable contacts). Please start your proposal stating what verification software you will use (a full report is expected with the data).
Some jobs may require additional manual research work which can only be completed through manually checking each site (we pay a premium cost for those records - if you do have the ability to manually collect please state this in your proposal).
This is for ongoing work of various jobs. Please base your quote on the cost for 1k (most orders will be 5-10k in total). IMPORTANT! Due to the expected volumes and delivery times you must be in a position to automate this job using relevant crawlers. Please do not reply if you only collect manually.
