Seeking GC for medium size renovation with some custom work

I’m looking for a GC for a medium size renovation of an apartment my wife and I are purchasing. We have relied on our architect to find contractors to this point but don’t feel enough options have been provided to get a competitive bid. The scope of work includes complete removal of kitchen to be replaced with HenryBuilt modular kitchen, cosmetic reno of 2 full baths, a decent amount of custom millwork, modest amount of new electrical and plumbing, painting, and a few other things. the challenge is timing, and that it’s a 4th floor walkup. We need the work to begin in December and be completed no later than end of March. I would appreciate any recommendations and would be happy to discuss the scope in detail with any potential leads. Thanks!
