Hello Handmaiden,
Good question. Since you are already attending an Orthodox parish, the priest there would be the person to get to know. And he needs time to get to know you. So attending services regularly and going to Scripture study (bonus) is a great start. Like any relationship, it takes time to develop. I will kindly disagree with you about his first priority being to his members. Of course, they need him too, but you are the lost sheep of the 99 and I think that this is first priority.
When I started attending, the priests (2) were very welcoming and the younger one took time to explain a lot of things (he was my weekly Scripture study). The older one had other priorities. So, it was a blessing to have two priests there although if there was only the older one, he would've taken time for me. It really depends on the circumstances such as how long have you been attending this parish? How is this priest's attitude with you? Does he stop to take some time to talk or does he brush you aside? Is he cradle or convert Orthodox? The fact that you are asking gives me the impression that you don't feel completely comfortable with him.
About going somewhere else....would you still be attending this parish? If so, then I don't suggest you look somewhere else for guidance. We need to be guided by the priest that is at our parish because, God-willing you convert, he will know you and he's the one you need to go to confession to. Like I said, we have to build a relationship. So, if it's been awhile, then I wonder why he wouldn't give you time. If you have been going a short time, then I think he's waiting it out to see what you will do. Perhaps he's waiting for you to make the first move and ask him for a meeting...maybe he feels that you may not stick around. There are so many dynamics to the situation. Is there trapeza after service: coffee and something to eat? That's a good time to sit down and chat a little. Please correct me if I'm wrong about any of the above. And if you feel comfortable enough, perhaps you can provide more insight to your situation.
I hope this helps, at least a little bit.
