ASK THE EXPERT: How are Online Travel Sites Regulated?

Monica McIntyre of Greenwich, United Kingdom asks:

My partner has a travel company (tour operator) which sells Latin American packages targeted to the Italian and German markets. We are joining in opening a new internet company with an e-commerce platform as a distribution channel for the same products to be sold to the US and UK online market. I need to hire a lawyer who could advice me on some e-commerce and travel licensing issues: 1. E-Business Legal requirements for a foreign company (Panama based) to sell online TRAVEL products to the US and UK markets. (e-commerce regulatory environment for our services in US and UK). 2. e-business tax: what are the tax implications of selling to US and UK online market if based abroad. How is this monitored?
