How to sell $10K+ development services remotely without meetings?

Our agency builds web solutions in the $10K-$25K range and some leads are in the high 5 figures. However, we are distributed, our costs are high while the local stage is flooded with low-quality services. There are no suitable customers here in general due to the limited market and low economical standard. As we are growing, our international customer base is no longer sufficient and we need to find new leads while our costs for high quality, education, licenses and such are still high. How would you approach selling or marketing $10K-$25K development solutions remotely, without any meetings with clients, or going to meetup groups and local events?
