If you're wondering how you should do these types of transactions without putting cash up front, the field is called trade finance.
Call your bank - most of them have a trade finance desk, or Google the term. A slightly cheaper way of doing it is to have a lawyer draft a terms of trade or supply agreement with either the funds in escrow with the firm or a bank guarantee.
Having your bank finance the trade is worthwhile as interest rates are so low at the moment. Common terms are 60, 90 or 120 day delivery with FED/LIBOR + x% (where x is the risk profile of your business - shop around to get prices) cost over the term.
The agreement would contain delivery timetables, warranties, customs clearance, liabilities, indemnities, guarantees, who pays what, etc. and you are protected legally without handing over tens of thousands of dollars or more upfront. These contracts are protected by law in almost all jurisdictions.
You don't finalize the transaction and pay for it until all conditions have been met and you have the goods in hand and have verified. The seller is trusting an international bank or a law firm escrow, and they should also have a lawyer or bank on their end (a trusted seller can receive the cash upfront for a fee with the bank picking up the risk, although I doubt any bank would finance a bitcoin atm without verified trade volume and a lower risk profile).
Talk to your lawyer and talk to your bank, having expensive items delivered without risking the full cost is a solved problem as old as finance itself and trillions of dollars annually are traded in this way. The extra $1k or so you'd pay on a $25k deal are worth it for the guarantee. If you ship goods regularly the costs are amortized as you can use the same contracts and finance suppliers. Don't deal with anybody shipping $20k+ valued products that doesn't deal with a bank trade finance desk or law firm and is instead asking for a bank transfer.
This is how most high cost goods are traded - from oil and other commodity supply contracts through to companies like Boeing and Airbus supplying planes, or GE supplying turbines for a power plant. Most people without experience lead into it thinking that buying something that costs $25k, $100k or millions of dollars is just the same as purchasing something at your local store just with bigger numbers. It isn't.
Bitcoin multisig transactions, or m of n transactions are also worth investigating as they cut the costs - although there is currently a lack of escrow/intermediaries who are as trusted as major law firms or an international bank. There is a huge opportunity in cutting the costs and fees associated with trade finance with bitcoin.
