Or you could send some money and your iPad to an online store front that says they can do it for you... and never get your iPad back or you money.
But wait... there's more.
If the iPad is part of DEP ( most enterprise / educational devices ) you have one more step in order to get full access to the device. Otherwise DEP will continually track / control the device no matter what account you enter.
[MOD NOTE]
The no way to get around an iCloud lock and discussion of methods to bypass that security feature will be fruitless and only devolve into accusations of asking help with a stolen device.
