right now i am building some freebe sites but i wanted to start doing some gallery posting to but am not sure if i should or not

i am making about 5 or 6 sales a week from my sponsor paysites right now and want to make moore but i dont know

it looks like making gallery sites will be a lot quicker to do and easier to submit to the gallery posts but is it easier to make money from them or should i stay with doing freebie sites or try something else to?
