Again, do slow down, my dear.
And why start your own search for critters and exchanges when a ready-made Forum already exists for members. It gives you access to a far broader critter range than the one-on-one you seek here.
There is a Share-your-Work Forum here in which you can now open a thread and submit your first chapter or 2,000 words or so for critique because you have raced towards and now reached the qualifying total of 50 posts.
Before submitting, however, I do suggest you take time to browse the Forum and check out the rules prior to submitting so you are aware of exactly what to expect.
Enthusiasm is always commendable but take note that frequent re-submissions are a turn-off for most critters, and your initial submission post should not be edited once critters start responding to it.
Good luck.
