Telephone - data update

we are a young company who have various data bases where clients have previously agreed to recieve quotes for insurance

we require someone to call clients to tidy the future sales call up

are you still interetested in receiving the call regarding insurance
would you prefer to have call now or wait until your renewal

maybe another couple questions - but NO SALES are required

we have around 1500 people needing called - if this exercise proves to be worthwhile then more data bases will be provided for the right person

pleas advise experiance / when you can do / how long it will take & costings
