Routing letters into wood.


See pic below - my mate owns the trailer below to tow behind his Jago Geep kit car - its made from the body of an accident damaged one.
At a show last weekend we had enquiries for replica's although most were thinking along the lines of rescaling it to sit on there own trailers chassis.
So, the solution we came up with was to build a new body from exterior grade MDF (compressed wood fibres impregnated with resin) which is easy to cut & sand, and has a surface & endgrain suitable for painting.
The only bugbear is the back panel with the 'Jago' logo. On the bodyshells, the panel is raised of the surface about 3/8", with the lettering sunk back in the same amount.
Our proposed solution was to fabricate the raised panel from 3/8" MDF with the curved edges & logo 'routed' in. The panel could then simply be stuck onto the trailer with adhesive & painted.
The problem is the letters - i've searched the web for templates, but all seem to be too small and in a basic typeface. Has any of you done anything similar with a router or had success making their own templates?
Any advice would be appreciated.
Cheers,
Swizz...
