How can a russian citizen get a visa for her husband. i live permanently in ghana and married to a lebanese.?

we want to travel for just about a week but i just cant get him the visa.most of the visa support agencies say they dont deal with lebanon. i cant do an invitation for him because i have permanent residence in ghana.he is my husband and i cant travel with him to my hometown,how pathetic is that.does anyone know any agency that can actually help me out or any other way to get the visa.
