Auctioning the signature for charity

Hello I'm here
I'm auctioning the signature of mine for 1 month all the amount collected from this auction will go to the M.B.D.A.V Sr. Sec. School (my old school which gives quality education to all for free and works on donation only)
I have neg. Trust so there is no signature campaign which is available for me so I decided to go for a charity.
Starting bid - 0.01 BTC.
Bid Increment - 0.005 BTC.
Ending time - 24 hour after last bid.
You have to pay only if I post more than 100 posts in these 30 days.
You can also choose to get it for a week instantly only for 0.03 BTC
More than 30 posts in this period of time.
If someone choose to go for a week the bids on the monthly campaign will be cancelled.
I use a escrow and accept payments after posting the above amount of posts and also provide you the receipt from the school that they got the donation from you.
