We do x for a or b every day. Even if the sentence is long, it is grammatical.

My suggestion is:

We find loans for people with bad credit or no borrowing history every day.

Edit: after thinking about this, I prefer:

We find loans every day for people with bad credit or no borrowing history.

All day, every day sounds like you might be bored. I would avoid it.

The adverbial phrase every day has to go at the beginning with a comma:

Every day, we find X for A and B.

In the middle, though here that would be quite awkward:

We find X every day for A and B.

At the end with no comma as given in my first suggestion.

Cambridge Dictionary: They usually go in end position.

They sometimes go in front position especially if we want to emphasise the adverb.
