A small town with a population of about 25K, is south of Portland by about 10 miles and resides at the intersection of two interstate freeways (5 and 205), Tualatin is what I think is a good choice.
It's very industrial and the city government seems to favor it. That said, there are many manufacturing facilities as well as industrial / light industrial parks throughout so there would be plenty of places to open shop.
The town itself is a good town to live in. It's laws are reasonable (no open container law so you can have a wine Wednesday party, walking between neighbor's houses for example) , there are no slums and no high concentrations of apartment dwellings - they're distributed around the city center with neighborhoods beyond that.
One of the states best gun clubs is just outside the city (TGCG), a few knife manufactures are close by with Warne scope mounts and Kershaw knifes being in the heart of town. Cabela's is currently building a store here too - the second one in Oregon.
Being close to the two interstates, it takes less than 10 minutes usually from anywhere in town to get on the interstate. From there it is a 20 minute drive to Portland, 30 to the PDX airport, 30 minutes to Salem and 90 minutes to both the coast (west) or mountains (east)
If you like the NBA, the Portland Trail Blazers practice here and many of the players / ex-players call this their home.
It's school district is shared with the neighboring town to the north, Tigard, but Tualatin has only one high school.
Lastly, it has way more churches than it does bars (my english professor once said you can judge a town - good or bad - by that radio, haha!!)
