Direct mail campaigne on a limited budget.

[Julie King]

Would a direct mail campaign of sending out 50 yellow letters a week be enough to start receiving calls?  My plan is to market these same 200 prospects each month.  Not sure if I should market to these same 200  each month, or market to 400 prospects and resend to them every other month.  I'm trying to stay within a budget of $200 a month.   I am looking to wholesale and this will be my 1st direct mail marketing campaign.  Any help or suggestions appreciated.
