sinage is brutal, no matter what you will get robbed, then there is the permiting and the landlord to fade.
i'm in germany right now, sometimes sinage can pay off in 89 i blew $7500 on a sign that paid off, in 88 i blew $5000 and it was useless.
you need to get the "Shop talk terms down" "Pan channel letters"<--u dont ant those
Monument sign etc, get the name of the sign then when you talk to sign guys you are in a stronger position, it also depends on the articulation of your location to the traffic, how visabe is it, is it worth anything ,
a spot we both know Hardtimes. on bellflower BL a sign there is useless nobody sees it, now at Gina Cue if earnie wanted more biz that type building coud use a good sign that would be effective.
a sign takes a long time to pay for, its a brutal racket.
best of luck, when im back i can help you in a few weeks, mid june at the very latest
