Hi Gang,
I am indeed the chairperson for Uke New Jersey!, the third annual of which will be held this year on August 28, 29 and 30 in Chatham, NJ (our regular venue in Morristown will be undergoing renovations from mid-June until September/October). Chatham is about an hour east-ish from Nazareth. The venue is booked and the contracts are out to the performers and should be in my hand next week. This will be a literal Ukulele love-in! (You heard it here first!)
I actually love the idea of your proposed event, and may have some information/insight that could be helpful.
The odds of getting any corporate sponsorship or involvement from Martin aren't very good, IMO, for a few reasons.
Martin gets around 50 requests a day for such things and as a result, they tend to only attend and sponsor the really big events. Philly Folk Fest, Merlefest, Newport, Grey Fox, etc... events that typically draw thousands of patrons. This is per my discussions with Chris Thomas at Martin last year. Dick Boak came to the first Uke New Jersey! with some instruments from the Martin Museum, but that was on his own time to support both me and Tom Walsh, whose book on the Martin Ukulele had just been published at the time.
For events that they actually sponsor (check their website for Martin Experience Events) everything is extremely Martin-centric, and understandably so, so sponsorship of a Ukulele event that doesn't have one of their "Martin Ambassadors" as a headlining performer doesn't really fit their MO these days.
Mid July is an extremely busy time for Martin as they are divvying their resources up for not only the summer festival season, but the Summer NAMM show in Nashville (usually the second week in August) as well as... the annual Martin On Main event in downtown Nazareth. This is a joint event produced by the Nazareth Chamber of Commerce, Martin Guitars, and the Unofficial Martin Guitar Forum each year on the first weekend in August. This year Martin On Main will take place on Saturday, August 1. Details for the UMGF weekend can be found here:

I have been to this event every year since it's inception in 2001 and it is a fantastic time (There are a few other UU members that attend as well), however, the main focus is on, unsurprisingly, Martin Guitars. While there are always some Ukes in attendance, the guitar is definitely the star. In fact, at last year's MOM event, there were only three Ukes in the Martin booth, although Kate Micucci stopped by and that was pretty cool (she grew up in Nazareth and her Mom still lives there).
So... if you all are intent on something in the Nazareth zone, I might suggest that you either aim for the Martin On Main event and take advantage of the pre-planned party, or shoot for something in late April/early May, make it very casual and unstructured and consider it a test for future events, or...
Come to Uke New Jersey! and enjoy the best of both worlds. A more traditional festival on Friday Night and Saturday with workshops, concerts, Open Mics, and camaraderie with Sunday set aside for freeform jam sessions and whatnot at a local park (I could even arrange for one of the featured performers to come do a workshop on Sunday).
For future reference, if there really is enough demand for a UWC/OUC style event in these parts, I know of a German swim club here in NJ that would be absolutely perfect for such a thing and would be willing to help with the planning for 2016 (my plate is already full for 2015). This place has a campground that allows a fire-pit, real showers and bathrooms, and a clubhouse with a licensed bar and a kitchen and a small stage.
