Your question is unfortunately a little unclear, but "have" is plural because it matches with "your friendship ... and your support," which are two things. It doesn't relate to "a great deal" at all.

You have two items – friendship and support – so you need the plural "have."

"a great deal" simply means "a lot" – it's quite a standard phrasing, suitable for business correspondence and semi-formal and formal usage.

In this sentence "have meant" is the present perfect form of the verb "mean".

"A great deal" is a very old (but still common) idiom meaning "a lot". As C says, it's a little more formal than "a lot".

Translation: Your friendship means a lot to us. Your support also means a lot to us. This is true now, and has been true for many years.
