OP, note that with current fee rates, you'll have to pay a lot. Spending 30 inputs takes up about 1000 vbytes. With fee rate at 45 sat/vb, that will cost 45,000 sat at least.
The only way to combine 30 UTXOs is to use them as inputs for a new transaction with two outputs (one of them would define a fee for miners while other - send the rest to new address).
Technically speaking, the transaction fee is not considered an output. From the perspective of the protocol, the sum of all the outputs minus the sum of all the inputs is the transaction fee.
