selling my strong leads without purchase

[Michele Rok]

When I gather strong leads without purchase, is it wrong to charge $750 for the lead before it is listed? Living in Ohio do I need a license to sell my source? If I am allowed to perform this deal what is the specific information I give to buyer for the lead? What information si I give to buyer before he buys. My guess is the numbers, the sqft, # of bedrooms and baths. Whether there is a buyers premium. How much information do I give to the buyer so he can make an informed decision before buying? Obviously I dont reveal my source until he buys right?
