Thanks lizardbtc for your kind reply. We're really considering BitPay, it looks very well known in the field and has many services (including fast exchange btc/eur btc/usd) that can help us.
If we decide to integrate Bitcoin, in your opinion, what is the best way to approach bitcoin communities?
Thanks again
There is always the paid way to use advertisements such as ads on bitcointalk.org , maybe bitcoin comunity on reddit ,
https://cryptocurrencytalk.com/, some cryptocurrency related websites such as coindesk , bitcoinmagazine, cointelegraph etc.
Put an signature campaign here on bitcointalk / twitter and fb campaigns / shoutouts ->

Of course social media - this even doesn't need to cost much if you know how to do it well: such as making a thread here, making an reddit post , twitter, fb, instagram ...
try to get listed on sites such as
http://bitcoin.directory/ ,
