if you can recommend a - any - swiss service provider being active for your branch for chf 1,000... please post his name and address... have some dozen of clients interested in such an unique chanceI'll have to remember you that the very best deal in the world is to register a Swiss branch of a foreign company.
From this point of view with £200 a year for a UK LTD and CHF1000 for the Swiss branch you are done with the company formation costs.
Instead of a UK LTD you could use an Estonian OU.
Which canton are you going to relocate to?
joke... to run a swiss company, being a "full" one or the branch office of a foreign company you need, apart from a registered office address, at least ONE swiss or eu citizen (individual, no service companes) RESIDING IN THE COUNTRY... and i'm sure any such person would charge some thousand swiss franks per year to take the full responsibility to act
and, don't forget the 35% swiss withholding tax not only on dividens but also on any FUND TRANSFER OUT OF THE COMPANY... of course recollectable (in full or part depending on the specific tax treaty between switzerland and your country of residence) if possible
don't think a public board is the right place to discuss such personal, not to say intimate, questions/projects
