Please assist in rewriting the following paragraph and make it sound professional and formal: The person who is needed for the training should be someone who will always be available during the physical eradication process and application of herbicides

The individual selected for the training must be consistently available throughout the physical eradication process and the application of herbicides. Additionally, this candidate should possess a laptop to facilitate participation in the online training sessions. Therefore, we seek someone who is both technically proficient with a laptop and able to be present on-site daily during the herbicide application. It is important to note that, in the absence of the relevant certification, we will be unable to proceed with the physical eradication job instructions.
