old direct mail leads/ working them as an agent

[Devin Mann]

i have a bunch of old leads from when i was trying to wholesale homes.  Much of them i talked down on price a good amount...  

Now that i am an agent i am going to try working those leads.  How should i go about it? 

I have most  of the info on the house, so how/when should i ask if they want to list? should i ever ask them over the phone if they would want to work with an agent like me? any scripts for real estate agents?

thanks.

PS: if you dont think i should ask if they want to list with me over the phone, how do i qualify my leads to make sure they are worthy to meet with in person?
