We are trying to build a single merged main lead generation database.
We have two ( maybe 3) main lead generation lists we wish to have merged, combined, de-duplicated and enhanced.
The lists are 10,000 to 30,000 contacts each.
I am looking for someone that can combine 2 or 3 databases, consolidate records
ie
ABC inc, 123 main st, 555-1212 and
ABC inc, 123 main st, 555-1111 becomes
ABC inc, 123 main st, 555-1212, 555-1111
Then De-duplicate the records.
Then enhance the records appending any additional data that can be found such as emails and mobile phone numbers.
Then be provided with the final master list in various formats (csv, comma delimited) AND as a google spreadsheet. Each final record MUST have a unique record identifier as these will be uploaded into mapsley.com
These lists cover an area in North DFW (Dallas Fort worth) in Texas, USA. It is of restaurant managers and we wish to get as many Mobile numbers and real email addresses as possible. If you have a means to provide actual VERIFIABLE email and especially mobile phone numbers to these managers make sure you explain in detail your capabilities to do so. Depending on the level of verifiable mobiles and direct emails we will add a tip for numbers and accuracy and use you again for the next lists. We already have google maps etc scraped, we need much more accurate data appended with real email and real mobiles.
The merge, de duplication and cleaning should be easy and straight forward,
I do not want any existing data destroyed except exact duplicates based on location but any delta info (555-1212 and 555-1111 in the example above) should be retained in the remaining record. The central defining data point for each record is the restaurant name and address.
