I would prefer you to repay some of your debts before you ask someone like me to take on more debts and risk on your behalf.
I wrote to you previously that you might find it easier to start an online business using E-bay and Ricardo. Your idea of opening an art gallery and hope for passing trade in Montreux is for me a very lovely but very risky project.
Starting an art gallery in Vevey - interested in sharing?
If you are selling
well on Ricardo, then yes as you have a market, but until then, I personally would avoid your project - I am very sorry but you must begin to live a realistic life.
You might want to start by advertising your own art here.
