Packages start at €250 for website design, you will have to add on a hosting plan (€60/year) and a domain name  (€30/year). 

In my opinion, the only real advantage of having a Facebook page is to be able to target an audience for your campaigns. You can target an audience by location (as close as a 1km radius from your business), by age, by smartphone device, by personal interests (i.e. personal passions, hobbies, favorite newsfeeds) and much much more… It is very powerful (and sometimes a bit scary).

I can make a logo for you for €95.  This includes: several original proposals to choose from, shaping the logo for rectangular and square/round formats and sending you all the files to be able to use it anywhere online and off-line.
