since its a s simple as that..........easiest way forward....
FIREWORKS has 2 rounded letters all are straight vertical or horizontal RECTANGLES....... do a lay out corel/sign program....that will give you the exact length of letters iam think 40 feet give ya 5 foot on each end......open....and as tall as you want i wouldnt go more the 36" tall.......but just for now lets use that.
on the layout in the sign program......pick a letter lets do the I..... GET THE WIDTH OF IT X 36", make a piece of coro/cardboard/masonite.......to that size. now you got every vertical segment of each letter.
take the O do the same thing with it and the S.......for the horizontials on the F & E, put a mark on the vertical 36" for the HORZONTIALS of the F & E......and also make a pattern for the R top........get the measurements from the computer lay out.....take those 4 5 pieces to each side, measure out where each letter will begin....strike a chalk line........on the bottom......lay up the verticals, R.......now you know the O & the S..ARE GOING TO BE LARGER ABOVE AND BELOW.......do not set them on the chalk line......it wont look right if you do.
lay up these stenciles draw a line around em.......now depending on how steady you are 3-4" roller......just stay inside the lines you drew bout an inch or so.............last thing......with a foam brush..you can cut to the lines..........with a good enamel paint like RONAN.........
50??? so you will 100 of these.......40 x 4= 160 X 2=320 sq ft. per unit paint+time no less then $7.50 sq ft $2400 a trailer.........so $24,000.00 total............hope they dont want em all done next week)))))
