I agree with baddog try a AVS first ,you dont have to worry about fraud,billing etc,and if you have only a small amount of content you will have all the extra material you need from the avs.
Many think that a paysite is the gold at the end of the rainbow,yes it can be but like any other business you need deep pockets to learn or take simple less expensive steps like baddog told you,make a simple AVS first,then move on as you get more experience
Im thinking of a solo site myself and if I do it you can be sure it would be with a large AVS to start
