So I have this idea (which I cannot disclose), I have sent it to a company named Davison.com (which I found via Google). They called me today (from the USA) and seem really keen on my possible invention. They seem to think it would be worth pursuing but they require a payment from me to do the checks on patents etc. This payment is for $559... I'm now stuck in a dilemma as the wife thinks it's just a scam to get money off me but im pretty sure my idea would be a success.
I know nothing about this company although their website looks pretty good so I'm a bit reluctant to hand over the money...so my friends I need some friendly advice....what should I do?
