The solutuion is very simple:

dont go for the search coils

go for the inductive proximity switches used in industries they come in two forms cuboidal(5cmx2cm) or cylindrical.Go to an sensor automation person.He will custom make it for you.I got one custom made for 300Rs. :D

Vegakit, mumbai also offers very small sized metal detectors, i have not used/worked on personally, but still you can check them over their site


All the best for your project :D
