$5,000 would look much better for 1,000 reviews... $50,000 for the 10,000 reviews you need.
I know it's a joke but 'someone else' started it... heheheh
P.S.:
Forgot to mention this >>>
Payment to be made full in advance and not after the entire job is completed (O my my!!!) as mentioned in the OP...
Of course, the job needs a silent pleasant atmosphere and the OP will provide such a well-furnished spacious bungalow (a nice palace/castle would do too), in-midst of extremely serene and beautiful setting in the Alps, and with airfare, lodging boarding drinks friends spa limo (including the tips) etc and other various miscl expenses (pay separately for various day and special 'night' time activities) taken care of -- in advance ofc!
Translation of MJ songs in any one non-English language would be charged extra (they would be instant hits in this English speaking part of the world/Youtube-comments).
Bonus: Free pings -- later!
Estimated time of completion of the job: Will let you know in about a year's time. Cheers!
