Hi! I'm a native Hungarian living in Hungary with ample experience in product/supplier sourcing, evaluating data and working on getting the very best deals. I work in customer service and help out with supply management as a part-time job, so I know the best tone to hit when reaching out to potential partners via emails and phone calls. (I actually have a certificate in commercial management, though I'm working more as an illustrator and translator these days.)
I'm not familiar with all of the products you mentioned, though for metal gazebos like the one in your example photo, I know a manufacturing company right from the top of my head! I've been in contact with them in the past about a different project. I'm confident I can source you at least 3-5 potential companies.
If they don't speak English at a high enough level for your needs, I'm happy to mediate between you guys; I have 10+ years of experience in translating and I'll make sure your needs and the company's offer is communicated clearly to both parties. (If it's just a couple emails, I'll gladly count them as covered by this project's 200 EUR budget. If more than five emails need to be translated, we can work out an EUR/word count rate for translations. We can discuss in more details.)
If all that sounds good, please contact me via chat to continue the discussion. I hope to be hearing from you soon.
Thanks, and have a great day!
