If you are asking us to check the site, giving the URL could be handy. If you are asking us to recommend a spell checker, you're probably best off pasting text in Word.
I ask software for my website www.rusmartworld.com I know in online have software for Spelling checkers on website...but I don't know where I can look.
I couldn't find any mis-spellings, but I agree that you should probably start by putting the text into Word before you publish. English is an inconsistent language, and you might be able to find a copywriter to proof your text for next to nothing. Little things like "We travel Russia a minimum of 3 times a year" and "Made by, Ukranian masters." are easy to fix. Nice looking site!
Writing for the web is tough. You may want to read some articles on writing sales copy. I would also change the text in the first block not to be blue on blue. It makes it a little hard to read. I wouldn't welcome them to the site either, I would make the first text on the site tell them what I can do for them. You have some great products and a nice looking site. I would add some products to the header and look into finding a good online writer.
