Dear Sir,
I wish to inquire about the availability of solar powerd LED and/or Video billboards in your range of products. I am advocating the use of these on a road project which I hope to be involved in,very shortly, in Nigeria. However, I realize its potential on highways and country roads which are remote from a source of electricity.
Finally, I will like to know if you provide after sales maintenance and what the conditions and cost implications are.
Thank you, Sir, in anticipation of your early response and cooperation.
