I would not recommend Bulgaria, Estonia or any other "dodgy" countries to form a limited company alas you yourself are from that country.
For a lot of big businesses simply looking at a company address where the country has no to bad rep is already a red flag. So you will have to do a lot of convincing work to do if you want to get funding.
Even a UK limited is the running gag in upper management since it needs next to no effort to create one and they are by default a risky to work with. In the past it was a common thing for dubious companies to create limiteds in the UK and this history is what drives the stereotypes of today.
That said I am confident that Germany is not the cheapest option tax wise and there is a lot of paperwork to do to get your company running. On the flip side you will inherently gain more trust with potential customers and investors.
