The problem with small European countries is that the US and international mysteries companies usually subcontract to local marketing companies to do the shops and the employees do them themselves. There are rarely any bonuses. You can offer to Bare whenever they do the green color gas stations a bid to drive and do them but the gas there is so expensive that unless you had another job that brought you that way it is too expensive. The best is if you are young and can island hop in the summer to do the shops they have at the islands like the arch hamburger shop, the Danish jewelry. The shops that are being shopped there are always international chains and usually are seasonal. I know that someone shops Exxon Mobil for the last 40 years in Europe but have no idea who the company is each time. Also all the international hotels are shopped by US based mystery companies and they prefer to give them to their shoppers that do them regularly and once you have done a hotel location you wont be able to do it again for at least 2 years for the European locations. Plus, the corporate office is interested how the hotel caters to wealthy tourists and usually they are not the locals. I actually did the money transfer shop in a couple of islands there because Bare had that summer the account and they paid me $100 per island. But they also offered $10 to do the arch hamburger shop at an island. Not worth it. Another problem is that some shops are being shopped by a different mystery company in the USA than overseas. Finally, in small European countries a local franchisee is the local representative for multiple brands, ie same person owns Dior, Chanel, Hugo Boss, etc so they do not bother to do anything and the revenue for the corporate company is too small as the very wealthy residents for that country will actually go to NY or Paris/London etc to make their purchases because they do not want the local people to know how much they spent. Whereas here Dior the company owns all their stores, shops them every month, and also do various special projects.
Try international service check, HS brands, gapbuster, maritzcx, ipsos (they have 2 websites) and marketforce but make sure you sign up for their international branch. I think ISC will be your best choice to find something.
