I'm sorry, but the reality is, It is rather difficult now to promote such projects. The society is not yet ready to work with them and invest in such. But all the same I wish good luck.
It is difficult to promote, but it is possible. I am sure that a project of this level should not have any problems with promotion.
There are a lot of ways to advertise and promote projects, any business can be successfully advertised, if it allows you to do the budget.
