Does my work for a contracting company that imposes usurious late payment penalties, with immodest pictures of women in its catalogs, make my money unlawful or questionable, and prevent me from performing Hajj with this money? And what is the ruling on a bank deposit in my name that increased in value from 15,000 to 40,000 pounds?

Selling villas and apartments by installments is permissible, provided it adheres to the Sharia (definition)-compliant regulations. However, the condition of a late payment penalty is null and void, and forbidden, because it constitutes usury (riba). Working in the marketing of contracts that include this condition is considered assisting and facilitating riba. Using catalogs that contain images of unveiled women is an additional sin. Bank deposits that yield a known increase on the original amount are forbidden riba, and this increase must be disposed of by spending it on the poor and needy.
