Develop a Bitcoin client to send fake transactions

I need you to develop some software for me. I would like this software to be developed for Windows . We are security form and looking for some developer to make us a BitCoin client that can send fake transactions to the chain. If you can get the chain to accept them that is a bonus if you cannot adn all they do is sit in the chain that is fine as well. All we need is for the transaction to be in the blockchain./bitcoin chain. Features are. Amount feild Bitcoin address feild. That is all. Just need a desktop program or web based program to do this task. A little more info. All the software has to do is send the transaction to the blockchain and let it be viewable. if the transactions can be confirmed that is good if they cannot and just sit there that is fine as well. Also note that there will be no balance in the senders wallet just the software sends how ever many btc the user inputs. Please be able to speak English
