Tax Return Bulgaria Assistance needed

Hi there,
In 2007 my husband and I bought an apartment in Bansko. we were advised that we had to set up a company in order to make the purchase , which we did . At the end of 2007 the same company told us that they would deal with all the end of year paper work that was required by the Bulgarian Revenue Authorities , and that all this was included in the price we paid to set up the company, obviously we thought this was a great service. It was only at the end of 2008 when we asked them if they had taken care of everything again that they told us that we had to pay them 300 Euro , we were shocked , but because the deadline was so near we did nt have time to find another company so we paid them . This year we have started to look for another company , and we have come across a website called wwwbulgarianaccount ant.co.uk , they are offering to do the same work for 99 pounds which sounds great but I would like to know if anyone else has heard of them or dealt with them ??
Thanks in advance.
