Satellite LNB install and pointing services in Northern Cal.

[buckstucky]

Does anyone know of any professional services that will service an LNB and or point a 12 foot dish to its proper satellite. I have used guys on my site and I think they have it pointed at Galaxy 31 but when I look at the output of the LNB on a spectrum analyzer I dont get the nice guassian hump Im used to seeing, and its sporadic and noisy and the DVB S300 receiver cannot lock or pick up a signal. I specifically bought a XR-3 to analyze the signal and I see a signal but its sporadic and jumps around between -40 and -60 dB (not steady) . Any help of getting someone who knows what they are doing would be appreciated.
