Sorry for the loss and delay but @examplens gave you the best option. If you want to attract the best hands for your job keep the payment with an escrow. This is because it will be difficult for unknown individuals to trust each. But the fund can be kept in the custody of a reputable member of the forum and payments will be made after the job description has been fully covered. A well-known reputable member @GazetaBitcoin is offering free escrow service and you can take advantage of it. You can contact him to get more information about using escrow services
