Many Freelancers fail at this first step and here is how you should write the proposal to avoid a rejection, especially in the case where you are a new freelancer with zero experience.
- Mention facts and figures about how you have been doing the same job at other places.
- Mention names of previous clients in case those were famous companies
- assure that unlimited revisions and 100% refund is guaranteed in the event of failure.
These facts and figures have to be in first two lines. make bullet points if you can not be so concise.
Main important thing to note is:
A proposal should be custom written for each employer and should focus on the value that you can offer to that specific employer.
