Lighting in a Detached Garage
Go to a real lighting store. Often times they'll consult with you free of charge if you purchase the fixtures there. They may cost a bit more, but are usually of higher quality than the big box stores and you get the advice. If you buy enough, sometimes they'll bend their policies a bit and give you contractor pricing. Clearly you need design input and they can give it to you, right down to calculating the lumens per square foot you need as well as other lighting options, such as task lighting.
Also, many lighting stores are small, locally owned businesses worth supporting. IMHO.
