I work from home and baby gets bored?

i work from home and oftentimes talk to customers so i cannot have the baby crying or making a lot of noticeable noise. my baby loves to be held, but she is almost 9 months and tries to grab everything on my desk and take my headset off my head if i hold her. she doesn't like being in a swing or walker or bouncer or anything. she crawls and it's safe for her to play on the floor near me, but she still wants me to pick her up and cries until i do. Does anyone have any suggestions to keep her from being bored. i cannot afford a babysitter or anyone to come help. i need to keep her entertained for about three hours until my husband gets home each day. she's a wonderful baby and really happy if she is getting undivided attention. any ideas??? thank you.
