This is what I suggest...
Try to find someone close...
• Search the Arduino Forum :: Community :: Local Groups
for someone in San Diego.
• Check the San Diego area for "hackerspaces".
• Check the Arduino User Map
Be willing to take matters into your own hands...
• Ask for help in Arduino Forum :: Using Arduino :: Project Guidance
• Provide technical details
: What board do you have? What scale is it (include a link)? What is this "LED screen" you reference (link)?
• Break the project into manageable pieces.
• Get your hands on the equipment and start playing with it.
Finally, the one thing you can offer is credit. Be prepared to share the glory.
