We specialize in electrical upgrades for vans, focusing primarily on lithium batteries and solar power systems. As an established installer based in Umberleigh, Devon, we plan to order components on a per-job basis to fit customer vans. We're looking for a reliable supplier who can provide quality products tailored to our needs, particularly custom solar panels with specific power outputs and dimensions. Our business operates mainly in the Marine sector, and we expect to sell between 10 to 50 units each month. Our fulfillment preference is monthly deliveries to maintain a steady supply for our projects. We found your company through word of mouth and are excited about the possibility of partnering with you in the Mounts & Wiring marketplace. Let's discuss how we can collaborate effectively while ensuring we receive reasonable margins and high-quality products.
