Developer for a NinjaTrader Strategy

Hi, we are currently looking for a developer how is able to code a Ninjatrader Strategy off of an already existing indicator that we will provide. We had bad experience w/ our last developer so we are resubmitting that project. The Developer should be able to provide own input and suggestions to refine settings. We are looking for a reliable guy that can finish the project within about 5 days. Signing of a confidentiality agreement is necessary upfront. Thank you, Phil
