This is frustrating. First, you advise that you are charging for contacts. Then you keep advising potential clients, wrongly, that their criteria are not met.
Then it is incredibly hard to find an email to ask you to stop doing this. On a Saturday, your phone number is not helpful either. Aiyee.
I understand your frustration. Clients can add their preferred qualifications that they would like freelancers to meet. If you do not qualify, then this notice appears, but that does not mean that you can't apply to the job posted.
If you apply, the client will receive a message saying that the freelancer does not meet the required qualifications. To hire the freelancer or not, is up to the client. If you think that you are perfect for the job, then I encourage you to write a winning proposal detailing why you are the best freelancer for the project. If you have any questions, please let us know. Thank you!
