this is very dear to my heart too.
i am not in the us, but am doing an online orthodox evangelism course from usa:http://evangelismcopticorthodox.org/home.html
(find the course on the list on the left, and there are lots of other resources on the page).
maybe, father, you could write to the organisers and ask if you could use some of their materials to train up evangelists in your area.
i suggest the following recipe for evangelism (to be taken a little lightly):
1. pray a lot
2. fast a lot.
3. pray a lot more.
4. hold Bible study meetings for anyone interested. it may be a good idea to do it after coffee hour / lunch on sunday to start with, then on another day as well as needed.
5. from these find deacons / sub deacons who can lead more meetings.
6. hold more meetings to which church people and outsiders can both come and ask questions about the Christian faith.
7. get the majority of the church attenders involved in Bible study, prayer and fasting, and a disciplined spiritual life.
(this one may take some time...)
8. make sure you do the majority of your services in the language(s) of the majority surrounding population.
(the congregation will have realised this is the right thing to do from all their time spent studying the Bible and so will not oppose this move)
9. take advice from the converts who have joined you (since you embarked on point 1 several years ago) on how to reach out to the surrounding people (who may be of one or more 'foreign' cultures) but avoid the temptation to give people teaching positions above their spiritual level just because they are converts and it 'looks good'.
10. start reaching out (eg. vespers followed by tea and cake and a short presentation on the church).
11. spend extra time with those who were originally in the church at the time of point 1 and encourage their spiritual gifts and their personal evangelism.
12. do some social outreach as well, such as foodbanks for poor people, visiting the elderly, chat with the lonely (students, umemployed etc.)
these are important things to avoid:
1. grouping people with respect to age (it's not in the Bible or the church fathers and it encourages selfishness). ok, teaching small children separately AFTER liturgy is ok, as they have a short attention span, but what's the big deal with singles groups, seniors groups etc?!
how is a young person supposed to learn if the old people are not with him? how can the old stay young and dynamic if their only friends are also old and so are all dying off?
i didn't escape stereotyping in the protestant churches just to find it creeping into the orthodox church too!
2. grouping people with respect to gender, also not a feature of the early church (i have always been fascinated with the teaching in 'men's groups', precisely because i wasn't allowed in! ok, i'm a sinner, but so are most other people!)
3. grouping people with respect to ethnicity, social class or level of education. (my least favourite of all!) again, this has no basis in Holy Tradition.
my current church (i move house a lot) has Bible study classes (in english, so not a big group comes!) and there are all sorts of people there. we are getting to know each other and benefitting a lot from the different cultures expressing the same faith. we have converts in the church from different faith and cultural backgrounds and it is lovely to meet them and to meet the majority north africans as well.
we also have Bible studies in arabic, which is great. i have not been yet, as i am still working on my arabic.
i don't mind people doing different outreaches in different languages, but the aim should always be one of integration into the host country language for those whose language skills permit (i have some friends who find english very, very difficult, so i understand the host language can't be used 100% of the time).
anyway these are just my thoughts, maybe they will be useful.
as the writer to the evangelism course pointed out, Jesus preached for 3 years before the first church was established, so if it took time for Him, we can expect it to take some time for us too!
