What i want from italki

I want learn english very well, more important for me speak english. I want to discuss any topic of conversation: about natural and interesting places in the world, maybe about work, cars and bikes. Early i tried to walk on the courses, but it was without results, i can't speak fluently, i speak very slowly, because courses in Russia is useless, but you can learn some grammar, i think its very bed (bad)...)) i need speak for my job, i work in very interest sphere: sales 3d printers. Its very popular in USA and is beginning development in Russia. I want to speak english to easily understand my college from US. Now i can't call them, but only through letters. I have never been in the US, i have seriously (seriously have) language barrier. This message i wrote without dictionary )))  (I also wrote this message without using a dictionary)
Waiting for comments))

i: Please, when using i, you must use capital I because you are talking about yourself and also, it is the correct term.

Your sentences need some correcting which is highlighted in orange.

But all in all, its not bad, but don't be discouraged. All you need is a few more practices and you'll be good...
