Posting parcels from Bulgaria

We are hoping to relocate our business from the UK to Bulgaria, we manufacture bespoke lighting and accessories that we ship worldwide. We currently use Hermes or Royal Mail.
Can anyone offer any advice or information about services from Bulgaria that we could use, most of out items are boxed, small to medium and usually weigh less than 2kg.
Any information would be useful, cost, reliability, speed etc.

Thank you

There's ‘EKONT' I've used it for sending parcels in Bulgaria but I don't know if they go outside the country.

There are a number of options. The two biggest companies are EKONT and SPEEDY. Proven and big enough. If you prefer to use an international company then you can consider DHL, BULPOST, InTime, FedEX and also there's a large number of smaller local providers.
