You might want to check eBay or with various commercial radio houses. You
may find they will have some used radio that they will setup for you that
will be type accepted. Several hams around here have dug up old commercial
radios and reprogrammed them for GMRS or other public service frequencies
they are authorized to use.
It is illegal to use Amateur radio equipment for GMRS transmissions. Local
organizations in this state which used to not worry about the use of
converted amateur radios on their service have now started discouraging the
practice and some have started requiring inspection of the radios volunteers
are using to insure that they comply with the rules. Violation of the rules
puts not only the operator at jeopardy, but also any related entity in which
the radios are used.
Here are a few excerpts from the rules.
95.129 Station equipment.
Every station in a GMRS system must use transmitters the FCC has
certificated for use in the GMRS. Write to any FCC Field Office to find out
if a particular transmitter has been certificated for the GMRS. All station
equipment in a GMRS system must comply with the technical rules in Part 95.
95.603 Certification required.
(a) Each GMRS transmitter (a transmitter that operates or is intended to
operate at a station authorized in the GMRS) must be type accepted.
95.621 GMRS transmitter channel frequencies.
(a) The GMRS transmitter channel frequencies (reference frequencies from
which the carrier frequency, suppressed or otherwise, may not deviate by
more than the specified frequency tolerance) are
462.5500, 462.5625, 462.5750, 462.5875, 462.6000, 462.6125, 462.6250,
462.6375, 462.6500, 462.6625, 462.6750, 462.6875, 462.7000, 462.7125,
462.7250, 467.5500, 467.5750, 467.6000, 467.6250, 467.6500, 467.6750,
467.7000 and 467.7250.
Note: Certain GMRS transmitter channel frequencies are authorized only for
certain station classes and station locations. See Part 95, Subpart A.
(b) Each GMRS transmitter for mobile station, small base station and control
station operation must be maintained within a frequency tolerance of
0.0005%. Each GMRS transmitter for base station (except small base), mobile
relay station or fixed station operation must be maintained within a
frequency tolerance of 0.00025%.
95.655 Frequency capability.
(a) No transmitter will be certificated for use in the CB service if it is
equipped with a frequency capability not listed in 95.625, and no
transmitter will be type accepted for use in the GMRS if it is equipped with
a frequency capability not listed in 95.621, unless such transmitter is also
certificated for use in another radio service for which the frequency is
authorized and for which certification is also required. (Transmitters with
frequency capability for the Amateur Radio Services, Military Affiliate
Radio System and Civil Air Patrol will not be certificated.)
(b) All frequency determining circuitry (including crystals) and programming
controls in each CB transmitter and in each GMRS transmitter must be
internal to the transmitter and must not be accessible from the exterior of
the transmitter operating panel or from the exterior of the transmitter
enclosure.
Good luck. I hope you find what you need.
