Need advise for 325i engine swap?

[GulbadinNaib]

I was given a 1988 325i convertible from a relative who didn't have space to keep it, and I want to restore it. About a year ago the fuel pump on the engine broke and I will need to get a completely new engine to swap. Anyone have any advise for what engine I should purchase/what I should look out for? I don't have an exact price point yet, but if anyone has ideas on different ranges for engine costs/what mechanics would usually charge for that engine, that would be greatly appreciated. I am going to be restoring the rest of the vehicle manually, but that I believe may be the most important first step on my journey.
