Hello,
I am a native Russian speaker and I live in the UK. I will be pleased to do this job for you, because Barcelona is one of my favourite cities.
I'll also be happy to blog about it - I'm going on a weekend break to Barcelona the weekend after next, actually. I'm originally from Moscow and I'll be able to target Brits and Muscovites as the blog audience, writing about tips and benefits of travel and relocation to Spain from these two countries.
Money-wise, I'd prefer to charge a fixed amount for filling the website. Depending on the amount of the content I can do it in 3 or 4 days. For blogging, you can pay me per entry. If you'd like me to do this in both languages, then I'd like to request the double price (for double work) minus 10% for the order.
We can negotiate. Please get in touch if interested. I guarantee professional attitude, deadline consciousness and a spark of creativity :)
Best Regards,
Maria
