Custom Development on Search Form (Someone with Prior Jobify theme Experience - who is available NOW)

We need someone to add some customisation to the JOBIFY wordpress theme. We need to be able to search by "Salary" bracket on the search bar. This means implementing it custom php etc. It needs to be done in a child theme/ or child function sheet so we can update when needed also. Its urgent - so we need you to start tonight - there's more work for someone who can do it ! Budget is low - £50 please respond with NEWDAWNRISE if you have read this ;)
