I am looking for a professional business grant writer

I am looking for an experienced grant writer with a demonstrable record of consistent not-for-profit art/business grant-writing success. I would like someone to rewrite our current grant application to meet our funder's terms and conditions requirements and use the vocabulary required in funding applications. The grantmaker would like to see the social impact as a result of their support as well as a clear business vision of growth. My budget is £100 plus £200 for a successful application with a total of £300. I would need the first version written by this Friday. We would also need to have a zoom conversation about the application.
Please bear in mind that if this application is successful we would like to continue working with you at your required fee.
