Hard to comprehend the problem as outdoor furniture and electrical cabinet are rather vague.
Lawn lighting? Gas grill? outdoor kitchen?
Can the OP reveal a bit more, eg the existing products I Eu, à photo or block ?
So far this entire project seems an impractical business model.
to design, build, ship from UK, EU a large heavy product to USA.
Cost of freight, paperwork, taxes, local regulatory compliance, would seem a huge expensive undertaking.
