What is the function of the search? Is it to find representatives who are local to the user? Yes. To allow members of the public to input their own postcode and see a generated list of those Financial Advisers nearest to them.
Which country do these postcodes refer to? All in the UK.
How do you plan to determine the distance between two postcodes, to know if they are within 50 miles? This is something I need advice on as I am very new to this. Do you intend to pay to use a third party service? Depending on the cost, I believe the organisation is happy to do this. Is the requirement to list records "within a 50 mile radius" a fixed requirement or is this arbitrary? This is arbitrary - it could be instead the three nearest to the postcode put into the search. Again, very new to this and looking for advice.
Does the database already exist, or are you planning to save the data on Squarespace? If it exists, please share the format of the database with us. Currently we have all the information saved in Squarespace. I didn't build the website from scratch, I now only administer it, so am not sure exactly what format it would be known as. There is a pen nib as an icon though.
I apologise for my ignorance on this!
