Here's an example of similar job I made not so long ago :
Could you provide more deteils on your job ?
Then i will give you exact time and cost estiminates shortly.
To lower your risks of hiring someone unskilled we could start with a trial paid milestone
for 1-3 hours and with lower rate for $12/hr.
I know you probably get a bunch of lowball bids
but do you really want to risk this project with somebody unskilled?
Please let me know your thoughts.
