So if I read you right, you want a found set of ALL the records, sorted from closest to farthest.
Create a number field for him to put his $$ search value in..."Search"
You already have the field of what you paid people "Fee"
Create a third field call "Difference" which is a calc field of: ABS( Search-Fee)
Then sort the records (probably is a list view would be best) by the "Difference" field Ascending. Have the freelancer name and Fee fields shown on the layout.
Is that what you're after?
Here's one approach:
In Find mode, enter the range of values you're interested in (e.g. 30...50). Perform the find and then sort the found set.
This works, now I'm struggling to add more fields into the list view, as of now there are only four fields and I can't figure out how to add more fields including "Difference". Besides that it works fine, thank you.
Just Drag 'em on using the field tool in Layout mode.
Or copy and paste the ones that are there (in layout mode) then double click the new ones to change thier designation.
Fitting them is often the bigger challenge...remember that your line hieght can be increased to fit two rows if you need them. Smaller fonts can help too, up to a point of readability.
