I am working as software technical consultant and my job description is to become pre-sales and delivery. Pre-sales is the one who meet new prospect, do demo and POC create proposal, while delivery is the one who do the real project.
My division only consists of 2 people (me and my colleague) and I always the one who do the pre-sales.
As we are going to have some projects in upcoming 2-3 months, is it professional if now I tell my manager that I don't want to do the pre-sales until all projects are settled?
